Common Liliana's Triumph, a sorcery as treating Diabolic Edict is the baseline for commons.

A Diabolic Tutor variant mixed with Demonic Consultation. It finds a card without shuffling, doesn't risk exiling your deck, and the number thirteen

­Dungeon Shade reprint, as flavourfully makes sense in a D&D world.

A Quickling. Has first strike, flash and haste to convey speed.

Yeah, the nonland permanent change was just a balancing suggestion that would require other changes as well.

Restricting or gaining some bonus if the exiled is wouldn't help with the ancient part I referred to earlier. That was what I was trying to go for with the high CMC.

The name is quite long. Would it be acceptable if it were just called "Seal Away" or "Contain Evil" or something like that? "Holy Bolt" is a D&D spell name... Maybe start working on a "Imprisonment" D&D card representation and then refer to the idea of sealing ancient evil in its flavor text?

Like

> Exile ~ ETBs exile target creature until CONDITION

where CONDITION "its owner has seven or more cards in hand" or "its owner controls seven or more lands"

u know, whatever.

Actually, I think just tucking the card far away into the library would work here as far as flavor goes. Ie. Unexpectedly Absent

It was supposed to just be a Journey to Nowhere templating update that references the fantasy trope of imprisoning some ancient evil entity in ancient times that inevitably escapes in the present. For resonance.

Changing to exile something large while dropping the Cmc down to one is a good idea since Seal Away is being printing. Although letting it exile any nonland permanent messes up the top-down flavour. Maybe limit it to exile black or red things?

IMO the card should somehow play on the ancient part of the name.

Maybe it could restricted to exiling creatures with certain CMC and higher? Then mana cost drop to , or include nonland permanents as well or something.

Thanks for the quote idea.
