Cleric of Chill Depths

The 1/3 body is built to eat an early swing and walk away, and the block trigger turns that survival into a tax: any creature that runs into it stays tapped through its controller's next untap step, taking a beater off both offense and defense for a full turn cycle. That is a Frost Titan-style tap-down stapled to combat rather than to a mana cost, which flips the usual math of racing. Blocking normally just neutralizes one attacker for one turn; here the attacker keeps paying for the collision on the turn after, so committing a creature to the red zone against this thing means loaning it out for free. The wrinkle is that the effect fires only when this creature blocks, never when it attacks, so it is entirely a defensive tool: it wants to sit back and dare the opponent to swing rather than trade in the middle of the board. The toughness-heavy statline commits fully to that posture, since the 3 toughness is what lets it keep blocking turn after turn without dying. It is neither a threat nor a hard answer; it is a speed bump that keeps costing the other side tempo as long as it stays on the battlefield, which is exactly the job the frame is shaped for.
