MTG Cheeri0s Deck by Brimba

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.

If this card is in your opening hand, you may begin the game with it on the battlefield. You have hexproof. (You can't be the target of spells or abilities your opponents control.)

Improvise (Your artifacts can help cast this spell. Each artifact you tap after you're done activating mana abilities pays for {1}.) Ward {4} Whenever this creature or another artifact you control enters, put a +1/+1 counter on this creature and it can't be blocked this turn.
