This card is a little confusing to me, but I think it has a lot of potential. For one, it’s graveyard hate on a stick. Sure there could be more efficient removal, but this card has a lot of subthemes to work with. Pirates for one, and +1/+1 counters as another obvious one. The explore trigger is nice, allowing you to either draw a land or he gets bigger and you get to essentially scry 1. Putting stuff into your graveyard though with a self mill in black is pretty potent for EDH, so perhaps you’ll be doing that more often. The Tracker isn’t amazing, but I think it has some prime uses in the right EDH decks.
