Quote Aura Fracture is not a good anti-bloodmoon spell. It costs the same as bloodmoon. If bloodmoon comes into play first you lose. If aura fracture comes into play first it's just a minor annoyance and just helps them with their wasteland backup plan.
This is why I said it was weak against U/r in the original post. What Blood Moon deck has a substantial Wasteland count?
Quote There are no good anti-blood moon cards. A deck needs an anti-blood moon strategy using cards like carpet of flowers, blue elemental blast, chill, fetchlands with basic land, and red spells.
A good anti-blood moon strategy for example would be two basic islands main, two blue elemental blasts sideboarded, and one carpet of flowers sideboarded.
The Carpet of Flowers requires green mana and that your opponent be playing blue. Not every deck has access to green mana and I would say
most Blood Moon decks don’t have blue. Aura Fracture is approximately as effective as the Carpet (it costs you mana but keeps your counterspells active), and is useful against other decks in the field (Dragon).
Quote Graveyard hate and hand hate is also stronger against Tnt than aura fracture(deals with both welders and survival). Graveyard hate is also strong against Dragon.
That depends on what the TnT is playing with. If he has Blood Moon and Survival the Fracture starts to look pretty good. If he runs a Sylvan Library too it starts to look even better. A card that single-handedly eliminates an opponents draw engine and most effective sideboard card is stronger than one that just targets the draw engine.
Against Dragon graveyard hate is one of the sideboard strategies they are most prepared to deal with. Stifle or Xantid Swarm stops all of it.
Quote Three mana is too expensive for a sideboard card that doesn't win you the game.
First of all, this isn’t true. Rack and Ruin doesn’t win you the game, it gives you a substantial advantage that
should win you the game. Even Energy Flux doesn’t win you the game. Second, Aura Fracture
does win you the game against Dragon unless they are using a non-standard sideboarding strategy. Even if they do it is at least as strong vs. Dragon as Energy Flux is vs. MUD.
