Resounding Thunder

Cast as written, it offers an unremarkable burn spell: three mana for three damage, asking a hair more than the rate justifies. The whole design lives in the cycling clause, and specifically in its cost. The cards in this "Resounding" cycle share a structure: a passable front face, and a back face you unlock by paying every color of a shard at once. Here that shard is Jund, and the payoff is a rare cycling trigger that does not merely replace the card but resolves an effect, doubling the three damage to six and aiming it anywhere. The wrinkle worth dwelling on is that cycling is not casting. The damage rides a triggered ability, not a spell on the stack, so nothing that answers spells on their way to resolution can interrupt it; you have effectively bought six points of hard-to-counter burn that also draws a card, with the steep three-color, eight-mana price as the brake. The trigger still demands a legal target, exactly as the cast spell would, so the discount buys no relief from targeting restrictions: it is paid entirely in fixing and total mana. The card amounts to a single question made playable: how big a mana pool, and how much color commitment, does a payoff have to demand before a six-damage cantrip stops being broken? The answer here is a full shard's worth, which is why the card reads as a curiosity rather than a staple.
