Kresh the Bloodbraided is on the battlefield with another creature, let's say a 1/1.
Kresh has the following ability:
Whenever another creature dies, you may put X +1/+1 counters on Kresh the Bloodbraided, where X is that creature's power.
The opponent deals 5 damage to both of them, which should kill them both. Will Kresh's ability trigger to make him a 6/6 and save him from being killed by the 5 damage?
