Most of the stuff i dont actually see making a huge difference. Keldeo got a new toy for its specs set allowing it 2hko checks like Celebi and [email protected]
I do think Cohagrigus will see more use now it gets Pain Split as a nice alternative to Jellicent as a bulk anti spin which opens up some more options for stall.
Sleep Talk tutor is useless unless they fix that damn Rest mechanic that they effed up in BW. =/
Stealth Rock tutor is nice opening up some options like SR Offensive lead Terrakion and whatnot. Might even find room on its offensive sets since all Terrakion sets are CC/SE/Filler/Filler anyway lol.
