[AI Opinion]

Nice designs 😄 I’ll compare to existing cards.

Soul Extraction: Slightly overcosted for Modern, fine in Commander. Vraska’s Contempt was 2BB instant exile + 2 life; yours is sorcery plus a 2/2. At 3B it’d feel perfect, at 2BB it’s playable but weak.

Steal Soul: Very weak. Four mana sorcery exile that only makes two minor trinkets is below Murderous Rider / Hero’s Downfall level. Either drop to 1BB or make the gems stronger.

Polymorph: Other: 3UU instant exile with five-land untap is very pushed, especially in Commander. Compare Settle the Wreckage or Reality Shift. At 4UU, or sorcery speed, it’d be safer. As written, probably too strong. 🐇✨
