Unbound Flourishing

X spells have always carried a scaling problem: you pay full price for every point, so the marginal counter, token, or point of damage never gets cheaper. This enchantment attacks that math from two directions at once, and the split between them is the design idea. On permanent spells, doubling X means every mana funneled into a Walking Ballista or a Hydra buys twice the counters or twice the body. On instants, sorceries, and activated abilities, it trades scaling for repetition: the X stays what you paid for, but the spell or ability resolves a second time with fresh targets, so a single Fireball or a big Stroke of Genius fires twice off one payment. The distinction is doing real reading: it checks how X is being spent and applies the amplification each kind wants, because a permanent wants to arrive bigger while a one-shot effect wants to happen again. Most payoffs would just bolt a flat modifier onto everything; this one respects that those are different problems. The gate is the cost of admission: nothing happens unless a genuine sits in the cost or activation, so the enchantment is inert next to a pile of generic value and only wakes up in a deck that deliberately routes its mana into variable-cost spells. Built around that constraint, X stops being a tax on ambition and becomes the fastest line to a lethal number.
