Suicidal Charge

The forced-attack clause is the whole mechanism, and it inverts what a -1/-1 board shrink usually does. A toughness debuff is normally a path-clearing tool: shrink the blockers, push through damage, trade up in combat. The catch is that it leaves the defender in control of the combat math; the opponent still chooses whether to commit, which creatures to hold, when to block. This one removes that choice entirely. By compelling every surviving opposing creature to attack, it turns a modest stat reduction into a one-sided combat-step ambush: you wipe out the X/1s outright, then watch whatever is left walk into a board you have set up to punish it. The two-color cost is the giveaway about intent: black supplies the attrition, red supplies the aggression, and the payoff lives with the player who wants the game opened up rather than locked down. It rewards a hand of held-back blockers or instant-speed removal, since the opponent's commitment is forced and the timing belongs to you. Where most edict-and-shrink effects in this color pair clear a lane for your own beaters, this one weaponizes the opponent's army against itself, an idea that reads more aggressively than the rate suggests. It is a niche piece, more a puzzle than a staple, but the puzzle it poses (how do you profit from creatures you do not control being forced to swing) is a genuinely different question than most sacrifice-for-value enchantments ask.
