I am curious why this is not a viable alternative to UB Death's Shadow. Between discard, Abrupt Decay and Assasin's Trophy, the deck has ample ways to interact with opponents while being able to win through sheer card advantage and the beefier threat that is Goyf or a Berserked Shadow.

Can't beat Snapcaster Mage. No version of Shadow has ever been that successful vs Tundra, but they pick up win % vs combo-oriented decks by mixing in discard, mana denial, and countermagic.

Your GB version falls firmly within the family of "Jammy Jams" [i.e. not tempo]. Most decks like this are bad versions of Grixis SCM/Kcomm/Hymn + Strix; which also happen to lose to said Grixis shell.

It's the classic Deadguy ale is fringe, add brainstorms and forces and now you have tier 1 deck. Brainstorm is so far and away the best card in the format it's dumb to not play it. That said I like the deck.

I see what you’re saying. These decks needs FoW and Daze to best combo consistently. Without that win percentage, the GB variants will never put up those kinds of numbers. That actually makes sense.
