Dusk Charger

Ascend was the keyword that asked you to commit to the board: not a single trigger, but a permanent toggle that flips once your permanent count crosses the threshold and stays flipped for the rest of the game. This Horse is the most literal expression of that bargain. As a 3/3 it is a body you would never run on its own merits; once the city's blessing comes online it becomes a 5/5, and the math the design wants you to do is whether your deck reliably reaches the tenth permanent fast enough for that bonus to matter. The trick is that nothing about the toggle is conditional after it fires. Most "as long as" buffs invite removal of the source: kill the lord, lose the bonus. Here the source is your whole board, and once the blessing is earned it cannot be taken back, so the +2/+2 is effectively locked in for the rest of the game even if your permanent count later drops. That is the structural difference between Ascend and a threshold ability like delirium or a count-the-board check like metalcraft, which can switch back off the moment your numbers fall. The body asks for nothing exotic in return: a wide, permanent-heavy deck gets a free statline upgrade on a creature it was already going to cast.
