Nivix Guildmage

Two activated costs sketch a complete grind-game creature, but the showpiece is the second: four mana every time to copy a single instant or sorcery you control, with no escalation and no discount. That fixed price keeps the copy engine honest, because Izzet decks that want to chain duplications cannot do it cheaply. What it buys is repeatability with a target reset, the small but real edge of choosing new targets for each copy, which turns a burn finisher or a tutor into something flexible on the stack. The first ability, a looter bolted onto a fragile 2/2 frame, is the more reliable everyday job: it smooths draws and feeds graveyard-matters strategies while you wait for a payoff worth doubling. Neither mode swings the board the turn the body resolves; this is a creature that accrues advantage over many turns rather than swinging tempo, and each activation asks for mana you might rather spend elsewhere. That mana strain is why it reads as a value piece rather than a clock. The copy mode is what people remember, but the looting is what earns the slot turn after turn before any big spell arrives to be doubled.
