for shamans, 2v2 is bleh, unless its resto+rogue.

3v3, youd be lucky to burn one down with trinket+ns+em+cl+ES. from there its 3v2, and Im pretty sure a cloak of skill stunlock rogue or a hunter would touch you.. not in a good way.

3v3 PoM+Pyro would be viable. trinket + POM + AM + pyro x2 + fire blast followed by silence of healer and improved arcane missiles x 2 = 1 dead. use your second silence, and trinket + POM+Am+pyro x1 + fireblast x 2 + third silence + arcane missiles x2 = 2 dead. 3v1 = gg.

3v3 felguard lock... *may* work. chain intercepts stunlock on healer; all out faceroll of dots, deathcoil agro, follow with fear.... maybe. it would be tough past 1800 imho.
