Let's say the Mass is 1 power, and it fights another 1 power minion. What happens?
Both take 1
damage each, which results in their simultaneous death. That triggers
Squirming Mass's
ability, which means its gains +1
power, but it's already dying, and merely gaining power isn't enough to save it. (Something specifically that saves a
unit from death would be necessary, like
Gilded Aegis.) In this example, both minions are placed in the
cemetery.
