Rivals Reckoning

Whenever a creature is dealt combat damage, put a wound counter on it. (It must survive the damage to get the counter.) Its controller creates a food token.
Creatures with wound counters on them can't at-
tack or block unless its controller sacrifices a food
and discards a card for each of those creatures.
At end of combat, exile each creature with two or more wound counters on it. For each creature card exiled this way, its controller draws a card.
