Equivalent cards (same color: white, and “effect-similar”):
1. “Odric, Lunarch Marshal” — Gives keywords to creatures during combat.
2. “Akroma's Memorial” — Grants similar abilities, but as an artifact.
3. “Akroma, Vision of Ixidor” — Gives itself keywords for each kind in your graveyard.

Reason: Few white creatures check your deck for keywords like “Priest of Possibility,” but these grant or gain multiple keywords in white.
