Gro-A-Tog's Psychatog grows by exiling cards from its own graveyard, so Tormod's Crypt can proactively strip that resource and also blunt any Fact or Fiction value, though it must be used before they start feeding Psychatog. Squee, Goblin Nabob is cut since it provides little pressure against a deck focused on countermagic and card selection rather than combat. This matchup mostly comes down to resolving threats through Counterspell/Foil and using Swords to Plowshares on a resolved Psychatog before it grows lethal. Keep the plan minimal since most of your sideboard (Naturalize, Warmth, extra Armageddon) is not well-positioned against their spell-based, low-permanent-count strategy.
