Urza's Incubator

When Ajani enters, create a 2/1 white Cat Warrior creature token. Whenever one or more other Cats you control die, you may exile Ajani, then return him to the battlefield transformed under his owner's control.

When you cast this spell, draw two cards. Flying Annihilator 1 (Whenever this creature attacks, defending player sacrifices a permanent of their choice.) Evoke 2U (You may cast this spell for its evoke cost. If you do, it's sacrificed when it enters.)

Devoid (This card has no color.) Return target nonland permanent you don't control to its owner's hand. Whenever you cast a colorless spell with mana value 7 or greater, you may exile this card from your graveyard. When you do, return each nonland permanent you don't control to its owner's hand.

Bestow 1G Enchanted creature gets +1/+1. Landfall — Whenever a land you control enters, you may pay 1G if this permanent is attached to a creature you control. If you do, create a token that's a copy of that creature. If you didn't create a token this way, create a 1/1 green Insect creature token.

Reach Whenever Six attacks, mill three cards. You may put a land card from among them into your hand. During your turn, nonland permanent cards in your graveyard have retrace. (You may cast permanent cards from your graveyard by discarding a land card in addition to paying their other costs.)

Flying, first strike When this creature enters, destroy up to one target nonbasic land. Its controller may search their library for a basic land card, put it onto the battlefield tapped, then shuffle.

Nonbasic lands are Islands.
