Svyelun of Sea and Sky

Merfolk spent most of the game's history as a tribe searching for a payoff that wasn't just another lord: plenty of cards handed out +1/+1, few handed out staying power. This one solves the problem from a different direction. The two-other-Merfolk clause is a threshold the deck naturally clears, and once it does, you get a 3/4 that shrugs off destruction, refills your hand every time it swings, and drapes ward over the rest of the school. That last line is the quiet backbone: a single generic tax on every removal spell aimed at your other creatures compounds fast when you're already up a card from the attack trigger and the opponent is staring at an indestructible attacker they can't profitably answer. The design tension is how the three abilities reward different amounts of board: the attack trigger fires the moment Svyelun swings alone, but the indestructibility demands a school around it, and the ward protects that school in turn. So the card scales with commitment rather than requiring it up front, and it punishes the classic anti-tribal plan of trading one-for-one, because the pieces that survive make the next attack better than the last. For a tribe that had long relied on going wide and hoping to outrace removal, this makes the wide board sticky, and it does so from a three-mana body that lands before the opponent has stabilized.
