Ghoti Coelacanth Consistency

With Coelacanth you can summon a lot of monsters and do a lot of synchros, this way you can create a strong board in the first turn, and break the opponent's board in the second turn, while also creating a good board. This deck guarantees that you have the cards to summon Coelacanth at your first turn 70% of the time.

The main ways of summoning Coelacanth are:

• Summon Lifeless, together with another lvl 4 or Reptolphin, use its effect to send Coelacanth to the GY, summon Dugares or Monoceros on the extra monster zone, and reborn Coelacanth with their effect
• Use Tremora's or Paces's effect to summon Coelacanth from the hand
• Summon two water monsters, then summon Abyss Keeper, and use its effect to summon Coelacanth from the hand
• Use Lifeless to send Coelacanth to the GY and reborn it with Monster Reborn
• Special-summon 2 monsters to tribute-summon Coelacanth from the hand the old way

The best combos occur when you have another fish together with Coelacanth (Monoceros, Abyss Keeper, or another random fish that can be normal or special-summoned from the hand throughout the combo), so that you can tribute it to negate any counter that targets Coelacanth (like Impermanence and Veiler). And always remember that you have to leave one card in the hand for Coelacanth's effect.

You can use some cards to search the deck for what you want:

• One For One searches for Beautunaful
• Beautunaful searches for Lifeless or Paces
• Small World searches for any monster using almost any other monster from the hand and Gameciel from the deck

Going First

After summoning Coelacanth, if you didn't summoned it using Monoceros, you can:

• Use Coelacanth's effect to summon Lifeless, Beautunaful, Paces/Shif and Reptolphin
• Summon Baronne with Coelacanth and Reptolphin, and buff it with Reptolphin's effect
• If you have Dugares or Abyss Keeper at the board, pop them with Baronne's first effect (I know this doesn't feel right, but I didn't found another easier way to get them out of the way)
• Summon Monoceros on the extra monster zone, using Lifeless, Beutunaful and the lvl 2 Ghoti
• Reborn Coelacanth with Monoceros' effect
• Use Lifeless' effect in the GY to put back Reptolphin and 2 other fishes in your deck, and draw a card
• Use Coelacanth's effect again to summon Reptolphin, Beautunaful and Paces/Shif
• Use a lvl 7, Beautunaful and the lvl 2 Ghoti to make Chengying
• Use a lvl 7 and Reptolphin to make Gymir, and buff it with Reptolphin's effect

If you used Monoceros to summon it at the first time, you just need to summon a lvl 4 fish instead of Reptolphin, and use it and Lifeless to summon Dugares to reborn Coelacanth the second time, then pop Dugares right after that.

At the end you'll have 3 lvl 10 synchros: Baronne, Gymir and Chengying, that can negate an effect, banish cards from the field and the GY, make your monsters immune to destruction and banishment, and 2 of them will have 4k atk if your opponent had 5 cards in their hand.

You can also focus on Ghoti combos, keeping the board ready for a Deep Beyond in the next turn, while also summoning an Askaan, that can come back from banishment after Deep Beyond's effect, and getting a Snopios from the deck

• Use Coelacanth's effect to summon a lvl 4, Beautunaful, Fishborg and Paces/Shif
• Summon Arionpos using the lvl 4 and the lvl 2
• Use Arionpos effect to banish Snopios from the deck
• Use Snopios effect to banish the lvl 2 Ghoti and bring it to your hand
• Summon Askaan using Arionpos, Beautunaful and Fishborg
• Use Arionpos effect banishing itself to get the other lvl 2 Ghoti from the deck to your hand (if you got Paces at the beginning, get Shif here, and vice-versa)
• Summon Snopios using its effect, banishing the lvl 2 Ghoti from your hand, and Beautunaful from the GY, and then target itself for banishing when leaving the field
• At the next turn you will have both Paces and Shif coming back, so you'll have double the chance of summoning Deep Beyond, plus you can summon an White Aura Whale
• After Deep Beyond's effect, use Askaan's and Snopios' effects to banish both Paces and Shif, so you can do more synchros in your next turn

You can also tweak it a little so you search for Zep using Arionpos' GY effect, keep Snopios in your hand, and you can summon Snopios banishing Zep at the opponent's turn to make a Whale, even after the Deep Beyond.

Going Second

This deck is not so good going second, but you can always use hand traps to stop opponent's combos in the first turn, and use Gameciel to get anoying monsters out of the way at your turn.

If you don't have any non-water monster in the GY, and used Dugares to summon Coelacanth, you can:

• Use Coelacanth's effect to summon Lifeless, Beautunaful, Fishborg and Reptolphin
• Summon Trishula using Coelacanth, Beautunaful and Fishborg, or summon a lvl 8 (White Aura Whale or Askaan) using Coelacanth and Fishborg
• Reborn Fishborg using it's own effect
• Summon Gymir using Trishula and Fishborg, or using the lvl 8, Beautunaful and Fishborg
• Summon Monoceros using Reptolphin and Lifeless
• Reborn Coelacanth with Monoceros' effect
• Summon N'tss using Monoceros and Dugares
• Use Lifeless' effect in the GY to put back Reptolphin and 2 other fishes in your deck, and draw a card
• Use Coelacanth's effect again to summon Reptolphin, a lvl 4 fish and Paces/Shif
• Summon Baronne using Coelacanth and Reptolphin, and buff it with Reptolphin's effect
• Summon Chengying using N'tss, the lvl 4 fish and the lvl 2 Ghoti

This way you can use Trishula's, Whale's or Askaan's effect and use N'tss' effect to disrupt opponent strategy while also building a strong board.

Again, you can tweak it a little bit to work when summoning Monoceros first and then Dugares.

If you used Monoceros or Dugares to summon Coelacanth, and you're not playing against water, you can also use Coral Anemone with Zealantis to clear the board:

• Use Coelacanth's effect to summon Lifeless, Reptolphin (or a lvl 4 if Monoceros was used) and 2 other random fishes
• Summon Zealantis using Dugares/Monoceros, Coelacanth and the 2 random fishes
• Summon Monoceros using Reptolphin and Lifeless, leaving the space below Zealantis and the space at its left free
• Reborn Coelacanth using Monocero's effect, again leaving the above spaces free
• Use Lifeless' effect in the GY to put back Reptolphin and 2 other fishes in your deck, and draw a card
• Use Coelacanth's effect again to summon Reptolphin and 2 random fishes
• Summon Coral Anemone using the 2 random fishes
• Summon a water synchro lvl 10 using Reptolphin and a lvl 7, and use Reptolphin's effect to buff it
• Use Coral Anemone's effect to reborn Reptolphin, and summon-lock you on water
• Summon another water synchro lvl 10 using Reptolphin and a lvl 7, and use Reptolphin's effect to buff it
• Use Zealantis' effect, to banish opponent's non-water monsters permanently, putting back Zealantis colinked with Coral Anemone

If you draw Reptolphin

Cry

With Dimension Shifter

Dimension shifter is a strong card to catch the opponent off guard and prevent them from building a strong board, but you also have to deal with it in your turn.

In this situation you can only use combos that summon Coelacanth from the hand (except using Tremora's effect), since it will be banished if you send it to the GY. Also, you can only use its effect one time, since it will also be banished after being used as material.

After summoning it from the hand, you can:

• Use Coelacanth's effect to summon two lvl 4 fishes, Paces/Shif and Reptolphin
• Use them to summon two lvl 10 synchro monsters of your choice

You can also substitute the Reptolphin with a Fishborg to summon White Aura Whale instead, banishing the opponent's monsters.

Also, after all, this deck is still a Ghoti deck, so you can just go on with some Ghoti combos, but don't forget that you may not have a fish on the GY to banish to retrive bigger fishes from banishment.

If the opponent negates your effects

Most of the time you'll have at least two lvl 4 monsters on the field. You can use them to summon a Bahamut Shark, together with Toadally Awesome, so you'll have some interaction next turn.

Sometimes you'll have a way to feint:

• Summon Lifeless and use its effect while already having Coelacanth and another card that can special summon it on the hand (like Tremora or after summoning Shthana). If it does not get negated and you have Tremora, you can send Shif to the GY, so you will have some interaction next turn
• Use Small World while having all the cards you need on the hand (if the opponent don't counter, you can always get from the deck the same monster you banished from your hand)

Another interesting cards

Abyss Keeper: Can be used to summon Coelacanth from the hand, and also be used to banish an opponent's card. It's helpful to avoid searching Coelacanth from the deck if it's already in your hand, and is a fish that can be tributed by Coelacanth's second effect. But can be anoying sometimes since it cannot be removed from your field so easily to open more room for Coelacanth combos.

Number 4: Stealth Kragen: Can prevent the opponent from doing actions that require specific attributes, can destroy opponent's monsters, inflicting damage to them, and can be reborn using a Stealth Kragen Spawn if you want. They can substitute Bahamut Shark and Toadally Awesome, or can work with them creating a new combo that summons xyzs instead of synchros.

Adamancipator Risen - Dragite: Can be used to negate an activation and destroy the card, which is like having a second Baronne that can activate its quick effect more than once.

Abyss Dweller: Can give 500 atk for all your monsters (since they are all water) and also negate GY effects the next turn, which can be a really bad thing depending on the opponent's deck.

Virtual World Kyubi - Shenshen: Can substitute a lvl 10 synchro, leaving behind a banish effect that is as anyoing for your opponent as Dimension Shifter after you already set up your board. Though it is an easy prey for Kaijus, Lava Golems, and cards like that, you can bring it back from the GY next turn.

Virtual World Beast - Jiujiu: Can act like a Snopios, banishing Shif and Paces from the GY to get a Deep Beyond next turn, while also being indestructible, since most of your cards are water and fish and you'll have a bunch of them at you GY after a Coelacanth combo. It can 

Red-Eyes Flare Metal Dragon: Can be summoned using Coelacanth and Monoceros, cannot be destroyed by card effects (since you will not detach materials from it anyway) and has an anoying effect that inflicts damage to the opponent every time they activate an effect.
