MTG Dredge Deck by Chad_Esq

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.

Cards in graveyards can't be the targets of spells or abilities. {4}, {T}: Exile this artifact and all cards from all graveyards. Draw a card.

You may sacrifice a nontoken blue creature rather than pay this spell's mana cost. Counter target spell.

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.)

If this card is in your opening hand and you're not the starting player, you may begin the game with Gemstone Caverns on the battlefield with a luck counter on it. If you do, exile a card from your hand. {T}: Add {C}. If Gemstone Caverns has a luck counter on it, instead add one mana of any color.
