Sea Stealth Attack, specifically the "(Genex Undine) SSA control" variant, is a deck that gives the player many choices during a duel, such as when to summon Genex Undine and what to send to the graveyard with it, which allows the player to adapt the strategy based on the matchup, opening hand, board, draws, and hand size compared to the opponent's. The tools in its toolbox include, the Sea Stealth Attack combo, spot removal with Atlantean Heavy Infantry, Synchro monsters, and the backrow lineup. Thus, knowledge of the meta is important with this deck. With this deck the player can be very vulnerable at the first few turns of a duel, gains strength as the duel continues, and can end up with an unbreakable board.
Because this deck has been out of the meta for a while, we do not have enough statistics on the deck to generate an up-to-date breakdown. See below for the most recent available decklists.
- Because Sea Stealth Attack must first check if Umi is on the field, you cannot use its effect to banish a monster in the same chain as its activation.
