Defenders of Humanity

The token math is doubled deliberately, and the second half is where the design lives. Pay X on the way in and you get X vigilant bodies immediately: a clean scaling enchantment that turns surplus white mana into a squad. The exile ability is the reason this is not just an X-token spell. Pay again, exile the enchantment rather than merely tapping it, and rebuild the same wall of Astartes Warriors from scratch. The catch is a pair of clauses that read like a design fence: you can fire it only if you control no creatures, and only during your turn. That first restriction carries the entire cost of the card's power. The ability is not a value engine you draw on turn after turn but an emergency reset, the button you press after a board wipe has scoured everything and left you empty-handed. It rewards the player who has just lost their army rather than the one who is ahead, an unusual place to point white's token-making, and the exile cost means the reset fires exactly once. The vigilance ties flavor to function; these bodies are meant to hold a line while still threatening to swing, and a defender who cannot attack is only half a soldier. White has a long lineage of enchantments that promise a second wave, but few make you earn that wave by first being wiped clean, then spend the enchantment itself to summon it.
