­Skylasher + Inan the Wanderer

Flash, 2/2 reach, prot blue: Costed as a grizzly... Wow. Methinks dev said "Holy crap, nerf blue!" that year.

Combine with... Very Indestructible Guy. At least you can "really freakin exile forever" him. And unsummon him. He unsummons himself to give you life when you cast another creatur.e Which is a nice little effect, good tension - rather overshadowed by the "Ok, I am completely unstoppable, equip me up to my eyeballs" ability. But still, nice tension - you can have him godlike, but only as your only creature.

Well, that's simple. A blue-nerfer that's your only creature. Let's be a little more sidelong in the nerfing - blue (and red) like spells more than other people.

And red's blue's other enemy, and being protected from your own spells sounds like a useful thing to have. (It's not, usually - though with Grip of Chaos would be; aww man, creating a cycle to combo with that would be great!)

For cmc6 red gets... about 6/5+upside? Mmm. Ok, this has a decent upside and a fairly large downside. So I think I can push that. Doing so moves it to rare though.

Annnd the 'only one of them' really leads to the obvious type and name joke. I think we'll replace 'high' with 'up' to not be tooo terrible.
