I'll analyze the Boros Energy vs Amulet Titan matchup and identify key sideboard cards.
Boros Energy is unfavored against Amulet Titan with a 41.2% winrate across 97 decisive matches in the last 60 days. Amulet Titan's ability to go over the top with Primeval Titan and generate quick mana advantages through Amulet of Vigor makes it difficult for Boros Energy to disrupt effectively, even with aggressive pressure.
Blood Moon appears in 59.6% of Boros Energy sideboards and is the primary hate piece for the matchup, shutting down Amulet Titan's multi-colored lands. Path to Exile sees significantly lower adoption at only 13.4% sideboard presence, likely because Boros Energy already runs main deck removal and Path ramps the opponent. Other relevant sideboard cards include Damping Sphere (38.2%) to slow down combo decks, Obsidian Charmaw (53.7%) for land destruction, and Molten Rain (12.3%) for additional land hate. Orim's Chant (60.0%) can also disrupt Titan turns but isn't specific to this matchup.
The data suggests Blood Moon is the standout sideboard card for the matchup, though the overall unfavorable winrate indicates Amulet Titan remains challenging even post-board.
