Atlantis, Last Stand of the Merlanteans

Spell/Field

If you have no WATER monsters in your hand or on your side of the field, destroy this card. All "Mermail" and "Atlantean" monsters you control gain 500 ATK and DEF and cannot be targeted by card effects. Once per turn: You can shuffle any number of WATER monsters from your hand into the Deck; add that number of WATER monsters from your Deck to your hand. Once per turn, during either player's turn: You can target 1 Rank 3, Rank 4, or Rank 7 Xyz Monster you control; return that target to the Extra Deck, then Special Summon the Xyz Materials from your Graveyard that were attached to that target, and if you do, declare a Level between 1 and 10, then those monster(s) become that Level until the end of this turn. Once per turn, during either player's turn, when your opponent activates a monster effect: You can discard 1 card and pay 2000 Life Points; negate that effect, then apply the corresponding effect depending on that monster's attribute. The discarded card is treated as being discarded to activate a WATER monster's effect.

- LIGHT: Until the end of the 2nd turn after that effect's activation, your opponent cannot add LIGHT monsters from their Deck to their hand or Special Summon LIGHT monsters from their Graveyard.

- DARK: Banish that monster, and if you do, banish all other copies of that card from your opponent's hand, Main Deck, Extra Deck, and Graveyard.

- FIRE: Until the end of the 2nd turn after that effect's activation, your opponent cannot activate Continuous Spell Cards.

- WATER: While this card is face-up on the field, your opponent cannot Special Summon more than once per turn. Until the end of this turn, any card sent to your opponent's Graveyard is banished instead.

- EARTH: All monsters your opponent currently controls, and all monsters your opponent Special Summons for the rest of the duel (even if this card leaves the field), lose 1000 ATK. Your opponent cannot activate Continuous Trap Cards or activate the effects of monsters Tributed for Tributed Summons.

- WIND: While this card is face-up on the field, cards cannot be returned from your opponent's side of the field to their hand. During the End Phase of this turn, send all cards that were returned to your opponent's hand this turn to the Graveyard.
