Dig Through Time is an interesting card. At a super-high 6UU instant, this has to do something good.
Look at the top seven cards of your library. Put two of them into your hand and the rest on the bottom of your library in any order.
This is actually a pretty solid card, even at 8 mana. Gravehate doesn’t interact with Delve much, as Delve exiles the graveyard as the spell is cast, not upon resolution. It’s hard to support too many Delve cards in one deck, but I’d be wiling to play this one by itself, honestly. A few of them in a control deck in Standard will be pretty solid. In fact, Wizards already thought of that and gave us a Narset control list, which you can see here.
The only thing I’m not a fan of is the flavor fail, where you have a card with Delve that puts the rest on the bottom of the library instead of the graveyard. Developmentally I understand as tossing 5 in the grave for Delve would be really strong, letting you cast a second Dig Through Time immediately for 1UU.
I think the card will be Standard playable, but I don’t think it’ll be worth a whole lot as far as I can tell. It’ll be played in standard Control decks as a way to dig for play-ables, but due to the necessity of Snapcaster Mage in other formats, it’s unlikely to see play anywhere else.
Until next time,
