Ulvenwald Bear

A 2/2 for three mana whose entire pitch lives in the sequencing of one entry trigger. The body it lands on is almost incidental: cast it after a creature has hit the graveyard this turn and the morbid trigger hands out two +1/+1 counters to any creature, the Bear itself included. That open target line is what gives the design its range. The counters can fatten the freshly-arrived 2/2 into a 4/4 with no death on the back end, push an already-large attacker over a blocker, or quietly upgrade something with evasion or an activated ability worth growing. Morbid here asks for timing, not deckbuilding contortions: a removal spell, a trade in combat, or a sacrifice the turn you cast it is enough to flip the condition, and a green board that wants to attack tends to generate corpses as a matter of course. The discipline is that the ability checks once, on entry, and never again. Play the Bear with no creature having died this turn and you get a plain 2/2, no second chance, no way to bank the counters for a better turn. That single window is the skill test buried in a common: it rewards a player who reads the turn and sequences the kill before the cast, and gives nothing back to one who plays the curve out in order.
