Gustave

When Gustave attacks or blocks, put 1 overcharge counter on this creature. Remove all overcharge counters from this creature: Gustave gains +X/+0 until end of turn, where X is double of the overcharge counters removed this way. If 3 or more overcharge counters are removed in this way, tap target creature and put a stun counter on it.{flavor} “For those who come after.”
