Why not White Mike and Black Mike? lol Seriously though

I love Cloudshift with zombies, especially on card:Geralf's Messenger, it's just mean. Have you ever tried Restoration Angel for the same effect but with the added board presence?

Restoration Angel might be really good! I love the 3/4 Flier blinking another creature!

I have indeed tried Restoration Angel . I actually used it before I realized Cloudshift was a thing. The only issue I had with Restoration Angel was the 4 mana cost. I enjoyed using Cloudshift a lot more, if only because it allowed me to keep up early/consistent pressure without breaking my mana at the 4 mark. Cloudshift allowed me, on the same turn I would cast Restoration Angel , the ability to still get off a Murder or other things necessary. In a deck that doesn't really plan on having much extra mana open, turn by turn, Cloudshift fits the curve a LOT better. There were many times I would cast Cloudshift on card:Geralf's Messenger just for more early damage against other aggressive decks.
