Way of the Cryomancer

Its self-made Jace can double a later cheap spell; slower and less immediate than Case of the Crimson Pulse (68), but a credible Izzet value engine.

Could be wrong if New cheap instants or sorceries could make copying one spell far more efficient than the current shell suggests.

Three mana for delayed value is a major cost in Pioneer; control can test it as a copy engine, but it is less reliable than established proactive engines.

Could be wrong if A dedicated spell-combo shell could value the copy activation much more highly than conventional control lists.

Modern's spell decks generally cannot afford a three-mana, sorcery-speed setup piece for one delayed copy; it is well below Birthing Ritual's (75) efficiency.

Could be wrong if Fast mana or an unusually potent spell-copy combo could give the Jace token a specialized home.

Even with Legacy's efficient spells, this is a vulnerable three-mana setup card whose delayed copy is too slow for most blue or combo strategies.

Could be wrong if Fast mana plus a specific high-leverage spell could make its one-shot copy effect a niche combo tool.

It supplies a Jace and lets multiple planeswalkers convert loyalty into spell copies, making it a strong engine in Superfriends and planeswalker-spells decks.

Could be wrong if Its adoption depends on decks having both enough planeswalkers and impactful instants or sorceries to justify a narrow slot.

A five-loyalty Jace offers repeated surveil or can duplicate a key removal or value spell, though it affects neither board nor combat immediately.

Could be wrong if Unknown format speed and removal quality determine whether the slow setup survives long enough to generate meaningful value.
