Sigardian Paladin

Green-white +1/+1 counter decks have never lacked ways to make a creature large; the harder problem has always been converting that size into a closed game before an opposing blocker or removal spell resets the math. This 4/4 answers by rewarding the act of growing rather than the size itself. The static ability keys off whether you've placed a counter this turn, not on how many counters sit on the board: put down the very first counter of the game and the light switches on, no accumulated stack of buffs required. On any turn you trigger it, the body attacks as a trampling, life-gaining threat with no activation and no setup beyond a single bump somewhere on your side. The activated ability grants trample and lifelink to one counter-bearing creature you control at instant speed, and its only requirement is that the target already carry a counter (placed this turn or ten turns ago, it doesn't matter). That makes it a combat trick: pointed at your biggest threat mid-combat, it pushes a blocked attacker through for damage and life inside the same step, or answers a surprise blocker after attackers are declared. The catch is the dependency both halves carry. The static side wants a shell that reliably deals in counters (adapt, proliferate, anthem-counter effects, the green one-drops that arrive pre-loaded), and the activated side needs at least one counter already on the target. Absent either, it is a plain 4/4 waiting for a reason to matter.
