Legendary creatures you control get +X/+X, where X is the number of legendary creatures you control. Whenever you cast a legendary spell from your hand, exile cards from the top of your library until you exile a legendary nonland card with lesser mana value. You may cast that card without paying its mana cost. Put the rest on the bottom of your library in a random order.

Whenever another creature you control dies, create a Treasure token. (It's an artifact with "{T}, Sacrifice this token: Add one mana of any color.")

As Deadpool enters, you may exchange his text box and another creature's. At the beginning of your upkeep, you lose 3 life. {3}, Sacrifice this creature: Each other player draws a card.

Destroy target artifact you don't control. Overload {4}{R} (You may cast this spell for its overload cost. If you do, change "target" in its text to "each.")

This spell can't be countered. Indestructible Toski attacks each combat if able. Whenever a creature you control deals combat damage to a player, draw a card.

First strike Creatures and nonbasic lands your opponents control enter tapped.

Landfall — Whenever a land you control enters, target player mills three cards.

Suspend 3—{1}{U}{U} (Rather than cast this card from your hand, pay {1}{U}{U} and exile it with three time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost.) Search target opponent's library for a creature card and put that card onto the battlefield under your control. Then that player shuffles.

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.) Skrelv can't block. {W/P}, {T}: Choose a color. Another target creature you control gains toxic 1 and hexproof from that color until end of turn. It can't be blocked by creatures of that color this turn. ({W/P} can be paid with either {W} or 2 life.)
