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.

+2: Put a +1/+1 counter on each Cat you control. 0: Create a 2/1 white Cat Warrior creature token. When you do, if you control a red permanent other than Ajani, he deals damage equal to the number of creatures you control to any target. −4: Each opponent chooses an artifact, a creature, an enchantment, and a planeswalker from among the nonland permanents they control, then sacrifices the rest.
