Taborax, Hope's Demise
Legendary Creature — Demon Cleric
Flying
Taborax has lifelink as long as it has five or more +1/+1 counters on it.
Whenever another nontoken creature you control dies, put a +1/+1 counter on Taborax. If that creature was a Cleric, you may draw a card. If you do, you lose 1 life.

If Taborax is dealt lethal damage at the same time as one or more nontoken creatures you control die or are dealt lethal damage, it won't receive a counter from its ability in time to save it.

If another nontoken Cleric dies at the same time as Taborax, you won't put a +1/+1 counter on anything, but you may draw a card as its last ability resolves. You still lose 1 life if you do.
