Kris, Stoic Hero

Partner with Hero (You may have two commanders if both are Legendary Heroes.)
If a creature would be destroyed due to damage
you may instead tap it if it is untapped and put a
mercy counter on it.
You and permanents you control have protection
from creatures and players with mercy counters
on them.
Remove {x} Mercy counters from Creatures if {x} equals 10 or more put a mercy counter on
target player
