Hour of Reckoning

Most board wipes charge a flat price and punish you for the army you committed; this one inverts the relationship. Convoke lets the creatures you intend to keep pay for the spell that buries everyone else's, and the single word "nontoken" is what splits the sweep down the middle. To a generic Wrath that clause reads as a mild hedge. To a deck flooding the table with Saprolings, Soldiers, or Spirits, it turns the seven-mana cost into a discount and the sweeper into a finisher: the chaff that pays for the spell is the chaff that survives it. The wider you have gone, the cheaper the cost evaporates and the larger the gap between what dies and what remains. There is a real string attached, and it dictates the line. Convoke taps your tokens to cast it, and because this resolves at sorcery speed, the creatures you tap are spent for the turn; a tapped creature cannot be declared as an attacker, so none of them are attacking that combat. The clean sequence is to fire on a turn the swarm was not swinging anyway, scrub every blocker the opponent has stacked, then crash in unopposed the following combat with the untapped remainder. The triple-white anchors it to heavily white builds rather than a splashable answer. Strip the tokens away and it is a clunky, overpriced sweep; surround it with them and it clears the table while leaving your half of it intact.
