I've been meditating more about the Tempo Threshold sideboard... A sideboard like: 4x REB 4x Submerge 2x Pyroclasm 2x Krosan grip 2x Gilded drake 1x EE wouldn't be ok? I mean, with Submerge Gilded drake is cool and in a desperate situation we can stifle him to have a 3/3 flyer; it's also useful against Ichorid because if you don't want to exchange it goes to the graveyard, removing bridges... The lack of Tormod's crypt could be bad, but stealing the opponents creatures could be interesting. What do you think?
