Dauntless Escort

The fog that survives a wrath. Where most board-wipe insurance asks you to hold up mana for a counterspell or an instant-speed protection trick, this one banks the answer in advance: a body that already sits on the battlefield, doing combat work, until the moment its controller decides to cash it in for a turn of indestructibility across the whole team. The sacrifice cost is the design balance here, not a cost you pay but the creature itself, which means the protection is non-interactive (no mana to tax, no target to redirect) but strictly one-shot. The trade is a 3/3 for a guaranteed blank against any destruction-based sweeper or targeted kill spell aimed during your turn, and against the symmetrical wrath the opponent casts on theirs, you simply respond by feeding the Escort to the stack. Indestructible does not stop sacrifice, exile, or bounce, so the protection is precise rather than total, but inside its window it is airtight. It rewards a board built wide and threatening enough that an opponent feels forced to reach for the reset button, then punishes them for pulling it.
