Gaea's Blessing is crucial insurance against Armageddon, letting us shuffle back key cards and refill after a mass land destruction reset, while also feeding Terravore's power/toughness less by keeping cards out of graveyards when needed. Cursed Totem shuts down Weathered Wayfarer's land-tutoring activation as well as Werebear's mana ability, but it does not disrupt their Treetop Village manland activations (note: Cursed Totem only stops activated abilities of creatures, and Treetop Village is a land before activating its animation ability). Thwart and two Daze come out since bouncing our own lands is far too risky against a deck built to punish us for having fewer lands after Armageddon or a Wasteland/Rishadan Port lock.
