Three cards stacked into one, each answering a different question about how much mana you have and when. Cast for four, it is a 4/4 trampler: a body plain enough that the beatdown is never the point. The value lives in the two modes that never put a creature on the battlefield at all. Reinforce turns it into a two-mana instant-speed pump from hand, dumping two counters onto whatever is already attacking; scavenge cashes the same card out of the graveyard as a sorcery-speed haymaker, adding counters equal to its power to a target. It is a counters payload wearing a creature's clothes, built for the +1/+1 strategies that want their late-game mana to keep converting dead cards into board presence.

The design's discipline is that the two counter-adding modes sit at opposite ends of a game and cost accordingly. Reinforce is cheap and reactive, a trick you leave up on a tight turn; scavenge is the expensive, once-only exile you spend after the creature has already done its dying. A card that would otherwise rot in the yard becomes a second spell, and both halves feed the same wide-counters plan that also, incidentally, leaves you a fine trampler if a body is simply what the board needs. The Beast never has to be good on its own because none of its three uses is asked to carry the card alone.
