Inside Information

At X=1 it is a BB three-drop that randomly converts one opposing top card, far less reliable than Stock Up; larger X is slow.

Could be wrong if A slow black shell that can exploit high-X casts or learn opposing top cards could make its variance acceptable.

Three mana for X=1 is too slow and random beside efficient disruption such as Duress and Thoughtseize; the high-X mode is clumsy.

Could be wrong if An existing black value shell may exploit opponents' libraries or life as a resource better than the supplied context indicates.

Its practical three-mana X=1 floor is unreliable and lacks immediate board control; Modern's cheap interaction leaves little room for it.

Could be wrong if A presently unshown combo shell could turn the free spell casts into a meaningful payoff despite the random hits.

Dark Ritual can make a larger X plausible, giving combo/value shells a testable payoff, but random hits and life costs keep it below Stock Up.

Could be wrong if If a shell consistently learns or manipulates an opponent's top cards, the card's variance and score improve substantially.

At X=3 or more it can turn life into several opponents' spells, and 40 life supports that; random hits from only one library limit breadth.

Could be wrong if The mana investment and inability to choose hits may prove worse than repeatable theft or conventional card advantage.

At X=2-3 it can cast one or more opposing spells without mana, creating a powerful swing, though BB, life loss, and random hits add risk.

Could be wrong if Unknown set speed, spell density, and removal determine whether the delayed random payoff is truly worth the life and tempo.
