I dont think green splash for rootmaze or a stax deck for stasis would be good. It doesnt stop ichorid or flash creatures. Orb of dreams is a possibility as mentioned but I think it hurts you too much to play, it would be too difficult to keep stasis going.
I think the mana drain option that was suggested with frozen aether is the key play. Tormods crypt is a good idea for main decking I think, as I put in my build mentioned before. Im still not sure about what a good land base is.
I'm running 4 Wasteland and 1 Strip Mine in my build; they've been working out great! The deck wants to stall the opponent as early as possible, so an early Wasteland or Strip Mine can really help and will prove valuable late game for destroying untapped lands once Stasis is out.
