­This feels OP. This is probably the third card I'd put in any white Commander deck, after only Sol Ring and Oblation. And Oblation is literally only better because it's an instant.

I take it back. This is only a little better than Oblivion Ring normally, although even that is a little too good nowadays. This feels more like Song of the Dryads, which is what pushed me down my previous line of thinking.

­Oblivion Ring is too good? They've just printed Banishing Light and Grasp of Fate.
I would put it in my White Commander decks too.

When was the last time an unrestricted O-Ring effect was standard legal? Banishing Light is a year and a half old. They seem to prefer more narrow versions now.

Didn't it just rotate with the advent of Battle for Zendikar? Or am I misremembering? You're definitely right that they didn't "just" print it, though. Sorry.

I guess that is how rotation works. It just feels like longer. In Standard right now, Silkwrap, Stasis Snare, Suspension Field, and Quarantine Field are the options. Those are pretty close to O-Ring in power. I guess it's just a combination of this being way better in Commander (my format of choice) than Standard and my lingering bitterness over the template change.

This is indeed pretty similar to O-Ring, though it actually reminds me of Darksteel Mutation (which was deliberately created specifically for Commander).

This is a lot harder to remove than Darksteel Mutation. Without a permanent type, you really need something super general like Planar Cleansing to save your thing.

This is literally the same level of difficulty to remove as Darksteel Mutation. They're both Auras. It takes the same removal to get rid of them.

I was referring to resetting the creature. I see more sacrifice effects than enchantment removal in many decks. Once you kill your creature, it's pretty common to see it again. Can't easily sacrifice something enchanted by this.
