Their whole maindeck is blue with no artifacts, so Blue Elemental Blast and Steel Sabotage have no legal targets and stay out. The second Thraben Charm comes in for its graveyard-exile mode, which shrinks Tolarian Terror's and Cryptic Serpent's cost reduction and can be a huge tempo swing when timed right. Remove Soul counters their creature spells outright, including Tolarian Terror and Cryptic Serpent before Ward {2} is even active, since ward only protects permanents already on the battlefield. Trim Prohibit, since its 2-or-kicked-4 mana value ceiling misses their real threats (Delver of Secrets at 1, but Terror/Serpent are usually cast well below their printed cost and the Serpents' true mana value is too high to matter), while Sunscape Familiar and God-Pharaoh's Faithful continue to wall their early clock.
