I tried EW tp8 landstill decklist with an additional Spell Snare in the main and it was golden. However, I played mainly vs. Oath, Jeskai and Pyromancer lists.
At first I was a little reluctant to try it, but playing with 4 MM and 2 Snapcasters, the Snares are "always" protected. I was really impressed by the performance of the card and the "security" it provides when holding it specially in a deck with so many counters.
I would try to upwards it to 3 if possible as you want it to be a hard counter in turns 3+ vs. Xerox style lists.
