空境影猫

If a creature with a +1/+1 counter on it died due to receiving too many -1/-1 counters, it dies at the same time that the counters are removed, and Skyclave Shadowcat’s last ability triggers.

You draw just one card each time Skyclave Shadowcat’s last ability resolves, no matter how many +1/+1 counters the creature had on it.

If Skyclave Shadowcat has a +1/+1 counter on it and it dies, its last ability triggers.

If Skyclave Shadowcat dies at the same time as another creature you control with a +1/+1 counter on it, its last ability triggers for that creature.
