Dungeon Crawl

Dungeon Crawl enters the battlefield with 4 Adventure counters on it.
{2}{g}, Remove an Adventure counter from
Dungeon Crawl: Tap target creature you control.
If that creature has Level Up, put a Level
counter on it. Otherwise, put a +1/+1 counter on
it. Then, if Dungeon Crawl has no Adventure
counters on it, sacrifice it. Activate this ability
only once each turn and only any time you could
cast a sorcery.
