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 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.

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.
