Such a sick deck mate! congrats, Don't have all the cards but well done :)

Using Bloodmage Thalnos, have enough to make a legendary any opinions on which to take? I was thinking Ragnaros, but perhaps you can enlighten me why I should take Ysera instead :)?

works great, early game if you get the right cards  you can sustain mid and late game. Good synergy and plentiful blockers. Even has a nice finisher.  Maintaining board control is manageable with the minion selection. I have played a fair amount of druid decks that were too combo dependent or lacked board presence throughout all 3 parts of the game. 

I feel this deck is under-rated and more people should give it a shot to have more feedback. I also put Ancient of Lore in for 1x Sunwalker.

What are some substitutes you would recommend for:

1x Keeper of the Grove

1x Starfall

2x Sunwalker

I'm surprised this deck didn't get more attention, pretty sweet. I play it with a few modifications concerning the legendaries; running Ragnaros, Bloodmage Thalnos & Cenarius. I'm easily at 90%+ wins at 3* Master. Most solid Druid deck I've played so far, destroys rush decks.
