Subbterror Behemoth Deck

This deck is quite easy to use, here is what you do with each main card

Hidden city/Terraforming : (Search Hidden City), Activate Hidden City, Add Guru with effect (if already have Guru in hand add Fiendess (if already have Fiendess in hand add a Behemoth)), next Set Guru, Use Hidden City effect to flip guru to DEF, with guru add Fiendess (if already have Fiendess in hand either 1. Add another Fiendess 2. Add Final Battle (Better earlier game) 3. Add Cave Clash (Better later game)) If added spell or trap, activate or set it.

Fiendess : Fiendess can be discarded to negate an effect or activation (NOT a summon) of a card (Spell, Trap or Monster) while you have a face-up subterror during either players turn. It can also be Summoned to use its second effect to set 1 monster you control to Special Summon 1 Subterror from your GY or hand in either DEF position.

Guru : Guru's FLIP effect is to Search a Subterror CARD (Monster, Spell, or Trap) from your deck. He also has an effect to set another monster (on either field) and himself, this becomes a quick effect if you control another "Subterror" card (it must be a face-up card though but activating a Subterror trap then chaining Guru's effect does work).

Behemoths : When you use Guru's, Fiendess's 2nd effect, Final Battle, Hidden City, or another Behemoths effect to set a card you can Special Summon them from your hand (During either players turn) But you can't Summon them when Fiendess 1st effect sets a monster because it is a cost.

The Extra Deck : You don't have to use this combination of cards, you should just use your extra deck for banishing by the effect of Pot Of Extravagance, but it like this for that it can still be useful.

Handtraps and Solemn cards : These are pretty basic to use but here is a list of what is in here and what else you could use

Ash Blossom : If a card is moved from the deck to the GY, hand or Summoned to the field, you can discard this card to negate the activation, it can also negate effects that draw.

Ghost Belle : If card card is moved from the GY to the hand, deck, banished zone or Summoned to the field, you can discard this card to negate the activation.

Droll and Lock bird : If your opponent adds cards from their deck to their hand (drawing counts) EXCEPT during the Draw Phase you can discard this card to stop them from doing this for the rest of the turn (It does NOT stop them from adding the card you activate) Remember that this Also blocks YOU from doing the same for the rest of the turn.

Sauravis : If an effect TARGETS a monster a monster you control you can discard this card negate the activation, it also has the effect that while its in the GY, when your opponents Special Summon a monster(s) you can return this card to your hand to negate the summon and banished the would be Summoned monsters.

True King Lithosagym, the Disaster : This card can be summoned by by destroying 2 monster on your field and in your hand including a EARTH monster and if they were both EARTH monster you can banish 3 monsters from your opponents Extra Deck (you choose which monsters are banished), this can heavily disrupt your opponents plays.
