Sling-Gang Lieutenant

At the beginning of your end step, choose one — • You gain 1 life. • Return target creature card with mana value 1 from your graveyard to the battlefield.

Whenever an opponent casts their first noncreature spell each turn, draw a card unless that player pays X, where X is this creature's power.

Flash Lifelink When this creature enters, exile up to one other target creature. That creature's controller gains life equal to its power. Evoke—Exile a white card from your hand.

Flash When this enchantment enters, draw a card. Creatures lose all abilities. At the beginning of the end step, sacrifice this enchantment.

Create a 0/3 blue Crab creature token. Investigate. (Create a Clue token. It's an artifact with "2, Sacrifice this token: Draw a card.")

Flash Flying When this creature enters, choose up to one target creature spell or planeswalker spell. Its owner puts it on their choice of the top or bottom of their library. Evoke—Exile a blue card from your hand.

Menace When this creature enters, target opponent reveals their hand. You choose a nonland card from it. That player discards that card. Evoke—Exile a black card from your hand.

Whenever you cast a noncreature spell, surveil 1. (Look at the top card of your library. You may put that card into your graveyard.) Delirium — As long as there are four or more card types among cards in your graveyard, this creature gets +2/+2, has flying, and attacks each combat if able.
