Stensia Uprising

The number thirteen is the whole design, and it is a deliberately awkward number to hit on purpose. Most permanent-counting cards care about a threshold you cross once and stay above; this one demands you land on exactly thirteen, no more and no less, which turns the token engine into a slow clock you have to actively steer. Each end step hands you another 1/1 Human, so the enchantment is both the payload and the mechanism that pushes your board past the target if you stop paying attention. The 7 damage is enormous for the cost, enough to end a game or kill a key creature in one shot, but the sacrifice is optional and only unlocks in that single-turn window, so the tension is arithmetic: you are counting lands, tokens, and every other permanent, timing removal or sacrifice effects to shave your count down to the magic number at the exact moment you want the payoff. It is a puzzle wearing a burn spell's clothing, rewarding a player who treats their own permanent count as a resource to be managed rather than accumulated. Left alone it is a modest token-maker; played with intent it is a delayed, conditional fireball that asks you to build the board that fires it.
