Vesuva in Extended?

[freakish777]

I was playing a match of Extended yesterday on MWS (I had a really bad Ug all counters, draw and bounce spells, win by decking opponent with Blessing recursion deck), and got absolutely mauled by a deck running Vesuva to copy Cloudposts and drop in Sunderings, Slavers, etc (I obviously have no idea how to play my own deck and mulliganned 3 times in two games).

Anyways, is Extended really slow enough that a player can drop Cloudpost turn 1 tapped, turn 2 Sylvan Scrying for Vesuva, turn 3 sit around essentially doing nothing, and turn 4 Trike/turn 5 Sundering?  Would anyone consider running a deck like that, I'm not exactly great in Extended, it seems too slow, but at the same time whats not to play about dropping Sundering?

I have suspicions that such play in Extended would be rewarded by Boros Deck, Zoo, Goblins or Affinity running you over by turn 4/5 (much like type 2 but faster), or Dragonstorm ignoring you entirely and just winning on turn 4.

It actually sounds pretty good in Tooth.  It would alleviate the need to run Tron.  Definitely need to test it out some but having 4 more Cloudposts might be good enough.

Though if I remember, Tron supersceeded Post as it got tooth out a turn faster.  something like that.
