Blue skies can be a very powerful deck in this format, so long as you are taking the right approach. No 3-cc cards in this deck, that's going to be a bit much. Here's the battle plan
1. play a cheap threat
2 protect it with everything you got.
Pretty simple concept right? Here's the deck
4 cloud sprite
4 flying men
3 balduvan conjurer
4 rushing river
4 force of will
3 mana leak
3 windfall (great synergy with gush and thwart
2 maze of ith
windfall is flat out broken, and works great with the whole return islands to your hand thing. I couldn't think of anything better than the rushing rivers, so I'm pretty open suggestions as far as replacements go.
