Another mirror-adjacent matchup against a very similar blue control shell. Annul is useful against their Powder Keg and any artifacts they bring in, giving you a cheap, efficient answer in a matchup defined by resource trades. Keep your full countermagic suite (Counterspell, Thwart, Arcane Denial, Daze) since games come down to who lands Stasis or Black Vise first and can protect it. Brain Freeze and Root Maze are trimmed as the lowest-impact cards since neither meaningfully swings a mirror decided by counterspell efficiency and card advantage.
