MTG Simic Control Deck by Rubn Maestro

Counter target spell. At the beginning of your next upkeep, pay {3}{U}{U}. If you don't, you lose the game.

Gift a tapped Fish (You may promise an opponent a gift as you cast this spell. If you do, they create a tapped 1/1 blue Fish creature token before its other effects.) Return target creature an opponent controls to its owner's hand. If the gift was promised, instead return target nonland permanent an opponent controls to its owner's hand.

Draw a card if an opponent has cast a blue or black spell this turn. Spells you control can't be countered this turn. You and permanents you control gain hexproof from blue and from black until end of turn. (You and they can't be the targets of blue or black spells or abilities your opponents control.)

When this creature enters, you may destroy target artifact or enchantment. Evoke {1}{G} (You may cast this spell for its evoke cost. If you do, it's sacrificed when it enters.)

If it's not your turn, you may exile a green card from your hand rather than pay this spell's mana cost. Destroy up to two target artifacts and/or enchantments.

You may reveal this card from your opening hand. If you do, when each opponent casts their first spell of the game, counter that spell unless that player pays {1}. Flying Whenever an opponent casts a spell, counter it unless that player pays {1}.
