IONA'S FAERIES - (Blue Yellow Flyers)
I've never made a deck that seemed to work as well as this one.
Skycaptains power up all your creatures. Get them down first.
Shadowsilk turns your faeries. (Plus Shadowsilk has sometimes been drawn as a 3/3. Very powerful with that protection)
Use the piranha tactfully as another piece of removal. I used it one game to kill a 24/24 Soul Eater.
Put the Piranhas next to the sky captains. Your opponent usually will try to kill those first. Or just sac a manta. You get so many.
You can opt for more mantas and less drakeriders or vice versa. I've tested and doesn't seem to influence too much.
Humbling Vision might seem weak, but in this deck it helps out a ton. I turned a Baeru to a 4/5 and easily killed it.
Nightmare anything else.
This deck plays in a control style. Sit back, but take control of the board in any way you can.
Iona commands her army of Faeries but can also double collect for you or body block.
Last thought: keep fatigue in mind. With Iona's smile and Shadowsilk you draw a lot of cards. But you can also usually play all of them. The decks average cost is very low thanks to the faeries. (:
