[+1]: Put a +1/+1 counter on up to one target creature.
[−3]: Target creature gains flying and double strike until end of turn.
[−8]: Create X 2/2 white Cat creature tokens, where X is your life total.
The number of Cat tokens you put onto the battlefield is equal to your life total when the third ability resolves.
You can activate the first ability without a target. You’ll still put one loyalty counter on Ajani when you activate the ability.
