It turns out that Magic players love casting spells for free, even if free in this case is pay seven mana for an artifact and cross your fingers you overcome the randomness to get what you want. The silver lining, of course, is whatever spell youre copying from your graveyard gets to stay there on the chance youll copy it again, unlike many cards of this ilk that exile the spell following the resolution of the copy trigger, so if you can find a way to finesse only one legal target for the Crucibles trigger (perhaps by ensuring the top two cards of your library are lands with something like Senseis Divining Top), then youll get to copy the same thing over and over

[[Digivolve] [Wormmon]: Cost 2] [All Turns] [Once Per Turn] When any of your opponent's Digimon suspend, trash the top digivolution card of 1 of their Digimon
Junji, the Midnight Sky is the latest in a long line of cards that can combo with Karmic Guide, and if youre in the market for a Dragon-based combo card, it can certainly fill that role
That means that when you cast it, you get to exile cards from the top of your library until you hit a nonland card with a lower mana value, and then you can cast that card for free
