The overall theme of the set is "everything is a resource". In addition to the overarching mechanics, I also plan on including one-off cards like this that utilize other resources you have in a similar fashion. I don't think this is quite pauper playable, but it's a tempting finisher in a heroic deck or other deck that burns through cantrips.

In limited, this is also used as a finisher in a Reap deck, though both Reap and Persist in white will fill up and use the graveyard in various ways.

Feels dangerous at common with unlimited uses, but then again you don't get to use it that often. Definitely an ability that I expected to see a once-per-turn limitation on.

Would red-flag, though it might be entirely fair.

I don't think it's redflagged by conventional standards, though it may be a bit too "bursty" in power level. It's mostly so I can have a decent common-level finisher that dedicated decks might want to take advantage of and build around. Thanks for the comment!
