Radiate

The fork that targets the targeter. Most copy effects in red duplicate a spell wholesale; this one reads the spell's targeting clause and fans it out across every legal target it could have hit. Point a single removal spell, a single bounce, a single buff at one thing, then redirect the whole table's worth of copies onto everything else that qualifies. The constraint is precise and load-bearing: it only works on instants and sorceries that target exactly one permanent or player, which rules out anything already multi-target and anything that hits zero. That narrow window is what makes the card a puzzle rather than a button. The obvious lines (multiply a removal spell across an opposing board) undersell it, because the copies have no allegiance: a symmetrical-looking spell becomes a one-sided sweep depending on what is legal to target and who controls it. The genuinely degenerate uses come from spells that read as drawbacks or shared effects, where copying them across every player turns a cost into a payoff. This is one of red's parasitic effects: it wins not by generating its own power but by feeding off the spell you cast first, which means the card does nothing until you have built the spell worth radiating. The reward for solving that constraint is a single instant that can resolve as a dozen, all aimed where the original could only point once.
