Mako Tsunami-Umi

Playing style

An "Umi"-focused Deck is centered on using the Umi Field Spells and the Umi related cards to make plays. The different Umi Field Spells each have different effects, and support different strategies. Typically however, Umi decks revolve around "A Legendary Ocean", who reduces the Level of all WATER monsters in both players' hands and on the field by 1, allowing Level 5 WATER monsters to be Normal Summoned without Tributes, and is also searchable by "Warrior of Atlantis".

The support for monsters that support "Umi" specify monsters that "lists "Umi" in its/their text". Additionally, the Spell/Traps associated with Mako Tsunami introduced in Duelist Pack: Duelists of the Abyss (i.e. "Sea Stealth II", "Kairyu-Shin's Dark Reef", and "Fish Sonar") all support WATER Normal Monsters in addition to "Umi"-supporting monsters, as the original series of Mako Tsunami's monsters are all WATER Normal Monsters.
