Gunkan

Gunkan is an Xyz-based archetype whose entire game plan flows outward from a single Normal Monster: Gunkan Suship Shari. Almost every effect in the deck requires revealing or controlling a copy of Shari to activate, so the first priority each turn is establishing Shari on the field or in hand, then using that presence to flood the board with Level 4 or Level 5 monsters and Xyz Summon into the fleet of warship Extra Deck monsters.

The engine assembles itself through a tight chain of Special Summon conditions. Gunkan Suship Ikura can drop from the hand the moment Shari is on the field, then excavates the top three cards of the Deck to find another Shari. Gunkan Suship Shirauo extends further by Special Summoning any Gunkan monster from the hand and then stacking additional copies of Shari on top of the Deck, ensuring later turns stay consistent. Gunkan Suship Shari Red accelerates the Extra Deck step directly, recruiting any non-Shari Gunkan from the Deck and immediately Xyz Summoning the corresponding fleet vessel without a Normal Summon. Gunkan Suship Uni handles situations where a Level 5 body is needed, converting a revealed Shari into two monsters on the board and enabling the Uni-class Super-Dreadnought, which can attack directly and neutralise opposing card effects as a Quick Effect during the opponent's Battle Phase.

The supporting spells and traps reinforce Shari access rather than providing independent disruption. Gunkan Sushipyard Seaside Supper Spot stacks a Gunkan card on top of the Deck every time a Gunkan monster is summoned, and its field-zone presence also grants the Shirauo-class Carrier's protection effect, making Extra Deck monsters immune to destruction by opponent's card effects while boosting their ATK by their DEF values.
