Getting a +1 for enchantments is traditionally a Green ability. I realize it's skirting things by specifically noting 'aura' but it is color bleed-and it's pretty strong, too, giving +X and flying for 2 mana at common.

I really don't think that the bleed is that bad. Blue can account for the flying part and white loves enchantments and artifacts, so I don't really see the problem here.

I honestly think the bigger problem is, who would play this? The reason that Equiptment is so much better than auras is because you don't lose it when the creature dies. One Doom Blade and you're out two cards.

Try some kind of Rancor-style recursion maybe?

If this has recursion a la Rancor, it'll be savage.

And why wouldn't someone play this in limited? In constructed it's a harder sell I'd agree but it still plays nice with a G/W/u enchantress kind of deck.

In limited you're getting a bigger creature with evasion for 2 mana: it doesn't suck.

Which is why I am concerned about the color bleed: if this just gave +1/+1 and flying then it would be doing what White does: stretching it out makes it more green and, even if that's acceptable, we ought to know that we've done it.

Honestly, I’ve felt for a very long time that the “enchantment wombat effect” has been in the wrong place. Green is the color of stripping things back to their true nature, not of alterations and artificial growth. While I don’t have a problem with green auras, I can’t think of a single reason why the color of Naturalize, Tranquility, and Creeping Mold should have creatures that want to be enchanted all that much more.

Blue was the Thran color in Urza Block, and it was the Thran that, as a race, wanted to be all ’roided out on auras. Blue’s supposed to be the color of alteration, so this all makes a lot more sense to me.

Circling back around to Soradyne Laboratories, Blue and white are the colors that have the closest ties to the Soradyne Corporation’s Consumer Products and Marketing divisions. White gets a bunch of Equipment support, blue gets a bunch of Aura support. Put the two together and you get this. Yes, it’s asking to get two-fer’ed. It’s also strong enough in limited to merit grabbing, and encourages more of the same without outright relying on it.

In a way though, I like that views like Mandroid’s will happen around this. Without the question of “is it good or not?”, limited picks and cards in general get boring really fast.
