Quote from pzbw7z »Rock is better versus Burn than either Jund or Abzan. It takes less pain from its mana-base and it typically runs three Scavenging Ooze and one or two Collective Brutality in the main-deck. Most Rock decks will have another copy or two of CB in the side-board.
Inquisition of Kozilek is always a three or four-of and it's the best card going against Burn. A quick Liliana of the Veil can also help deplete a Burn player's hand.
Field of Ruin and Assassin's Trophy can sometimes color-screw Boros long enough to make a difference.
Burn-hating Jund and Junk lists could be built, but it just didn't happen all that often because it made the deck worse in other situations.
A strong draw from such a deck can be unbeatable for Burn. Those draws aren't so common that 2-15 is an expected outcome, and I think that Burn is still favored to the tune of 55:45 or 60:40 against "Tarmogoyf decks" of any variety. I don't buy that Rock is a lopsided matchup so heavily favored against Burn that it's approximately as favored as Burn vs. Tron.
