Thrive and Thrash

This Simic Deck isn't very Simic. When you look, there are 0 Simic and only 6 different Gatecrash cards. Wizards also put Thragtusk and Wolfir Silverheart in the deck. Together those cards cost 26 dollars at Planeswalkers Library not even counting all the other cards. This deck MSRPs at $24.99 and that looks strange.  Here is the questionable Thrive and Thrash.
