Dreamway Guardians is a good card to keep because the deck is a little slow to get minions out, so they help a lot with a bit of mitigation at the start of the game. Breath of Dreams is also good because you're almost guaranteed to holding a dragon minion, and having an early extra Mana Crystal is never a bad thing.
Just a quick dragon deck for druids that I put together for fun. It went 4-2 at the Silver tier. Ysera is pretty unnecessary, I mostly put her in because she’s thematic for druids. The buffing spells in this can really make some monsters, especially if you can manage to keep 3 or 4 minions on the board and the Arbor Up!
