This card is very strong. Yes, I think I will sacrifice my Gravecrawler to grab a
Dark Confidant out of my deck on t3. Or perhaps I'll wait until turn 4 to grab an
Ophiomancer variant for infinite fuel for this. In addition, it helps set up creature based combos for things like the Persist deck. This thing grows based on the number of creature cards in your graveyard, so it could also just serve as a 5/5 for two sometimes.
Basically, it looks like Dredge got a new toy.
Cancel with cycling. I think there may be a place for this in my list, but I'm not sure yet. I really like my
Dissolve variants, but that doesn't quite mean that this will play similarly or better. You only get to look at more cards with this if you cycle, so it is just
cancel when you use it as a counter spell. The jury is out on this one.
