Deck profile and explanation :
Main:
3x Engraver: The 1 card Fiendsmith combo, and by far its most important card.
1x Lacrima: 1 card Fiendsmith combo.
1x Lurrie: A key part of the Fiendsmith combo. You add it and discard it by Tract, summon it from the GY with its own effect and then link it of into Requiem.
3x Enchantres: 1 card adventurer combo.
1x Gryphon: The adventurer combo's omni negate.
3x Diabellstar: The Azamina combo starter.
1x Diabelleze: If you have in your hand after you finished your Azamina combo, it can be a brutal floodgate for the opponent. Otherwise just discard fodder, but still pretty good.
3x Nibiru: The most important hand trap against decks like Ryzeal, Maliss, Branded, Fiendsmith, Fire King etc.
3x Veiler: Could've just played two since imperm does the same better, but still really good against Ryzeal which needs to be handtrapped multiple times to be finished off for good.
3x Ash Blossom: The best hand trap of all time.
1x Ogre: Again, you can just remove it since it is the weakest hand trap here, but still can come in clutch against decks that can summon bosses even after multiple hand traps.
1x Mourner: Veiler on a diet. Can also be used for some burn damage if you use Ogre on the same monster.
3x Tract: You almost always side for one. It can be used as a Fiendsmith starter, but is still better for being searched by Engraver and then doing the lurrie shenanigans.
3x Aramesir: The 1 card starter and THE MOST IMPORTANT card in the Adventurer engine.
1x Faithful Adventure: A key piece in the Adventurer combo, you search it off of Aramesir and then use it to search for Gryphon
1x Dracoback: I didn't use it a single time. Just side it out.
1x Called by: Your saving grace if you get hand trapped in an important spot.
3x Deception: A key combo piece for Azamina.
3x Wanted: The 1 card combo starter for Azamina.
1x Hallowed: The most important card for the Azamina engine.
1x Paradise: a good way to set up your Fiendsmith combo during your opponent's turn, otherwise side it out.
3x Imperm: The third best hand trap in the game (After Ash and Fuwalos). Also can't be Called by.
1x Azurune: Bunny
Extra:
Sequence: Used if you go for Des Irae instead of Caesar in your Fiendsmith combo.
Requiem: A key piece in the Fiendsmith combo, whether you go for Caesar or Des Irae.
Moon: Can turn any two bodies in the field into a fiendsmith combo.
Masquerena: Alright, I guess? It's not used in any of your combos, but can be good if you get handtrapped multiple times and can't continue to summon S:P during opponent's turn to banish thier bosses or starters.
Little Knight: The best link monster in the game. Already explained.
Rabbit: If you can't continue and have two bodies on the floor, this little bunny is potentialy your only saving grace.
Des Irae: Can negate multiple monstars if you do go for him, but kinda clunky to set up.
Necroquip: idk honestly, I guess it can be used(?), but I didn't know.
Aerial: idk man. Guess it can set up a Fiendsmith combo but I don't actually use it.
Mu: Very good Azamina card. You can go without her but she's still good sometimes.
Silvia: The omni negate of the Azamina combo. Insanely strong.
Caesar: The main anti-Nibiru monster on the field. It can be used either as a summon negate to mess with your opponent or as a material for ZEUS and/or TY-PHON.
Evolzar: A pretty good monster negate, but Caesar is still a bit better.
ZEUS: If you went second, you can summon it on top of Caesar in your MP2 to make an insane boss monster and further ruin your opponent's chance of making a comeback in turn 3.
TY-PHON: The best Xyz monster in the game. It not only has a good removal effect, but it can also render all of your opponent's bosses useless and make them pretty much just big beatsticks.
Deck pros and cons:
Pros: The deck has three engines which are all 1 card combo (omni)negates, and all can summon that one negate in under 5 special summons, so you're completely Nibiru-proof.
Cons: The three engines have no way of searching each other out, so if you want to go with all three combos, you need three special cards in your hand.
