Immediately improving the wording for ambiguity.

This looks like in many match-ups it could end up being a dead card... perhaps a fit for a commander product or such.

Maybe? I mean, "creature" is going to hit most decks. So this is "Destroy all..." of either enchantments, artifacts, or planeswalkers. Which is pretty darn powerful. (Ok, not quite that good, 'cause they MIGHT be willing to lose all their creatures1. But.)

Say it was a scenario where you wanted to destroy their enchantments and they have lot of creatures and enchantments - which is a prerequisite for this to do something there btw. You are at best getting an one-sided Back to Nature in there. This being a punisher effect means you are always going to get the worse deal. Seems situational and not particularly powerful to me.

Sure; it's going to hit one or two of whichever non-creature threat the opponent is playing. That's pretty good.

It's not "8 mana win the game" good; but, you know, this only costs 2. It's decent.

I'm not disagreeing with power level concerns. But I'd like to point out that a direct comparison to Back to Nature wouldn't be fair. Back to Nature is always a dead card if your opponent doesn't have enchantments. And Back to Nature hits both players.

To be honest, this card would be a monster in multiplayer. I'm down for cards being printed just for multiplayer. Also, personally speaking, I'd play with this card if was balanced or not, since it looks fun. And hey, maybe it is balanced. Couldn't say.

Loving the discussion.

Some of my considerations:

• I started this at a much higher cost, bringing it down from Damnation/Day of Judgment costs bit by bit considering the many any ways this could be "dead" - most simply by an opponent playing only creatures.
• If an opponent plays any single of the other three types this becomes a vastly superior (since flexible) Mire in Misery.
• If your opponent happens to control two creatures and two of any of the two types it already is a guaranteed two-for-one.
• Against certain decks/strategies/game states it's so good that two mana is a bargain...
• ... playing against Voltron/Boggle? The decision between sacrificing the creature or all the Auras attached to it is easy, but results in a similarly devastated game state.
• ... facing affinity & similar? Choose artifact and creature and all artifact creatures are gone no matter what they pick.
• ... facing a planeswalker like Elspeth, Sun's Champion or Gideon, Ally of Zendikar who are unapproachable behind a wall of tokens? Either option solves them.
• ... facing a longer game against enchantment-based removal e. g. Pacifism and Prison Realm.
• I think of this as a 1-game-match mainboard-able sideboard card (at least) that only gets more likely to be useful as the game expands noncreature playable permanents e. g. recently colored artifacts leading to more pushed colored designs.
• Even if this gets you only a sacrificed Aura out of them, that sometimes is worth something.

Overall I want this to be a card that is less dead than Naturalize, but with a higher ceiling and some interesting consequences just taking it into account as something to play around.

I also gave it the additional upside to be bonkers and political in multiplayer, so I am certain this will find a home even if it doesn't hit the mark for Standard Constructed-equivalent game play.

ADDENDUM: One last option I considered to give this some additional gravy was going hybrid - unfortunately black shouldn't be able to pick the artifact/enchantment option. Alternatively mono-white is an option, but I strongly feel this card is not worth less than two mana.
