This Manifest mechanic is gonna be a rules nightmare with cards like Cloudshift.
edit: now that I think about it, it can be borderline broken outside of Standard. All you have to do is topdeck a bomb, manifest, flicker it and - voila! - a cheap way to cheat any bomb onto the field, regardless of whether it's a Planeswalker, Enchantment, Creature, Artifact or Land.
That will require a reasonably costed, repeatable method of triggering Manifest and a reasonably costed, repeatable method of flickering.
The only Flicker effect in Standard right now is Skybind. Are you really going to play Skybind? Seriously?
And in Modern you require both a bunch of I/S Flicker effects and for your opponent to be kind enough to not kill your 2/2 extremely vulnerable bomb.
Maybe in some EDH deck like Brago, King Eternal could we use some of these, since he can then Flicker them and generate CA that way, but even that's a pretty bad line of play. There are better things to be doing with his ability.
I said "outside Standard.". And outside Standard, top deck manipulation is easy to manage. I haven't researched the number of ways to flicker permanents (not just creatures) in Modern, but the ones off the top of my head are both cheap and undercosted. And from what I've seen, so are the spells that Manifest. And, obviously, you would only Manifest something the same turn you could flicker it.
Any card that lets you cheat out bombs for cheap has always wound up being a chase card. What's unique about the manifest method is that it can be any permanent. The only other cards I can think of that do that let your opponent do it as well, and one of those had a successful archetype built around it. This strategy is cheap, effecient and one sided.
Soulfire Grand Master compares nicely against Satyr Firedancer, which many thought (or still think) is red's most powerful 2-drop in the game.
I'd say they're evenly matched, with Master coming out ahead because he doesn't die to Erase.
