I've been playing this token druid deck for a while and have seen some success with it. I'm not really good at optimizing decks so I need help finding cards that would be good in this deck which is a token/aggro deck. The match up's I struggle against are Quest Shaman and Reno Mage. I don't know if it's the deck or how I play those match up's that's costing me the game. But any tips on cards that would boost my chances against these decks or play style to counter them would much appreciated. I find myself losing either because I lose the board or run out of steam. I'm sitting at rank 13 at the moment but I'm stuck because of those two decks.
