Queen Mother Ramonda
Wearing the crown usually means holding it briefly. The draw-a-card reward for being monarch is priced against the near-certainty that someone connects in combat and takes it from you, and the swarm decks built to nibble your life total are precisely the ones that shred a monarch's tenure. This 3/5 breaks that arrangement on arrival: it crowns you, then forbids the entire class of small attackers that make monarchy fragile from swinging your way. What can still threaten the crown are the genuinely large creatures, and the five toughness is built for exactly them, standing in front of the 3- and 4-power bodies that clear the prohibition and blunting the mid-sized swings that would otherwise pass the throne along. The elegant catch is that the wall and the card advantage are welded to the same status: both hang on being monarch, so the moment you lose the crown once, the combat lock and the draw engine collapse together. That coupling is what keeps a five-mana throne-keeper from being a lock rather than a default. Lose the monarchy and there is no protection to win it back; the card only defends what it is already holding. It belongs to a strand of white design that reshapes who is allowed to attack rather than killing the attacker, answering aggression by rewriting the combat step instead of pointing removal at a creature.
