League Guildmage

The second ability is the one that earns a fragile Wizard body a place in a spellbook deck: a repeatable fork that scales with mana value, paying X generic and one red plus a tap to copy any instant or sorcery you already control, with the freedom to pick new targets on the copy. The catch is that X must equal the original's mana value, so the comfortable cadence is doubling cheap spells, a one-mana burn or a two-mana cantrip, while forking a five-drop asks for a payment most boards cannot float alongside the tap. The first ability anchors the floor, converting the Guildmage into a card-advantage outlet when nothing on the stack is worth saying twice. The tension between the two activations is the whole design: one grinds, one bursts, and a 2/2 across two colors can only crook one finger per turn. The new-targets clause is where the ceiling lives; copying your own removal spell manufactures a second instance to point at an additional threat, splitting a kill spell across two blockers or landing a second burn on a fresh target rather than steering the original anywhere. This is Izzet's standing contract with its engine creatures: soft in combat, liable to die before it untaps, but offering a runaway loop to a deck disciplined enough to protect it and stocked with spells cheap enough to copy on curve.
