Fully Grown

A pump spell that leaves something behind. The +3/+3 is the loud part, but the trample counter is where the design actually lives: a combat trick usually spends itself on one attack, and once the turn ends you are back to square one. Stapling a permanent trample counter to the burst means the mana you spent keeps paying out. The creature that grew this turn stays a threat that pushes damage past chump blockers every turn after, and any future pump you find gets multiplied by the trample you already installed. That reframes the card's timing. You can hold it for the ambush blowout like any instant, dropping a blocker into a fatal size, or you can cast it early as a semi-permanent upgrade and accept that the +3/+3 half is a throwaway rider on the counter you actually wanted. The two modes rarely align, which is the genuine tension in an otherwise simple card. It rewards decks that already treat counters as a resource to accumulate, where a single trample counter is not a one-off but another entry in a growing pile, and where a big ground creature was always the plan and the missing piece was a way to make its bulk connect.
