Undead Augur

Coven — At the beginning of combat on your turn, put a +1/+1 counter on up to one target creature you control. Then if you control three or more creatures with different powers, draw a card.

Whenever another Zombie you control dies, if it didn't have decayed, create a 2/2 black Zombie creature token with decayed. (It can't block. When it attacks, sacrifice it at end of combat.) At the beginning of your end step, you may sacrifice a Zombie. If you do, draw a card.

Whenever another creature you control dies, investigate. (Create a Clue token. It's an artifact with "2, Sacrifice this token: Draw a card.") Whenever you sacrifice a token, surveil 1. (Look at the top card of your library. You may put that card into your graveyard.)

Whenever another Human you control enters, put a +1/+1 counter on Kyler. Other Humans you control get +1/+1 for each counter on Kyler.

For each different power among creatures on the battlefield, choose a creature with that power. Destroy each creature not chosen this way.

Enchant player Nonlegendary creatures enchanted player controls have base power and toughness 3/3 and lose all creature types.

Flash Flying Whenever this creature enters or attacks, choose any number of creatures with different powers. Those creatures gain double strike until end of turn.
