Faerie Macabre serves mainly as an efficient flying blocker against their small value creatures like Augur of Bolas and Murmuring Mystic's tokens, since this Jeskai list has minimal graveyard synergy worth attacking beyond stray Archaeomancer returns. Their plan is grindy card advantage via Ephemerate loops and Preordain/Lorien Revealed, backed by Counterspell and Skred as answers, so you want to play a longer game and avoid overextending into Skred, which scales with their snow permanent count. Trim a couple Mulldrifters and a Nyxborn Hydra for the more proactive blocker since raw card advantage matters less against a deck that already out-draws you. Keep deploying your mana-producing walls to both block and eventually overwhelm their board with bigger threats.
