See Challenge # 128.

Wasn't sure how to capture the idea of wizards studying the connections to the spirits, but if we can think of them as further enhancing creatures imbued with spirits, you can imagine something like this. Hopefully it's normally simple (with simple P/T boosting auras), but will occasionally have interesting interactions.

It's only for one turn so there's fewer memory issues, although it's already quite complicated.

You could also have other aura-related creatures, eg. ones that filter your library for auras, or reduce casting cost, etc.

Wheee. That's a really cool ability. Feels undercosted, though ICBW.

Actually I want a or legend with this ability to be a commander :)

Thank you!

I really wasn't sure on the cost. It seemed like getting this, another creature, and an aura powerful enough to be worth copying into play was a sufficient hurdle it didn't need to cost any more. But it might be too powerful with some particular auras in which case it could easily be up-costed a bit.

You could drop Ordeal of Thassa on something and just not attack with it, so the Ordeal sticks around to keep copying and drawing 2 extra cards a turn. Mini-Arcanis!

Ooh. Very neat.

You could also just use this on Flight of Fancy. Thankfully [?] there aren't too many ETB auras kicking around, so these interactions require mixing sets that are pretty far away from each other.

Though, this ability begs for some new ETB auras to be made. A couple cantrips, perhaps, and some other minor effects. I agree with Alex. The ability is too special to waste on a 1/1 uncommon.

There are a bunch of cantrip auras already. Most notable Spreading Seas but also Sisay's Ingenuity and a cycle of mostly bad cards from Theros - Nylea's Presence being among the better ones.

Note that Nylea's Presence demonstrates "attach it to target creature you control" isn't always going to work. Spellweaver Volute demonstrates that it's going to be hard to find a sufficiently general phrasing for that!
