Crazed Boom-Bot

At the beginning of your upkeep, put a charge
counter on Crazed Boom-Bot, then deal damage
to each player equal to the number of charge
counters on Crazed Boom-Bot.
When Crazed Boom-Bot dies, it deals X
damage to target creature, where X was the
number of charge counters on it.
"Definitely a goblin design."
