Bonus entry for Challenge # 030. Inspired by Alex's Blade of Vengeance. I don't know if Alex recognized it and chose to do his own thing, or if he just missed it, but equipment transforming into auras and/or auras transforming into equipment is pretty damn awesome. The word attach or unnattach doesn't need to appear on the card anywhere! I just had to make this card... and I messed up by not fulfilling the challenge on a previous card anyway.

Also, I did a verboten thing by making the axe a black artifact, without giving it a black converted mana cost. But, the concept was just too black to leave as a normal artifact... I wonder how many people that would upset?

That was indeed my motivation for making auras that turn into equipment or vice versa - but I did that on Nebulous Rage, not Blade of Vengeance. In fact, I was interested in that before I even wrote Multiverse: one of the cards in Sienira's Facets (which was the inspiration for me to write Multiverse) was Soulblade of Honour. It's certainly not a clean implementation - it's pretty horrible... (Although it was good in the set, which had things that cared about being equipped and/or being enchanted, and the card types you controlled, etc.)

But yeah, I suppose I'll grudgingly concede that this is one thing that DFCs enable that wasn't really possible before :P

This particular take is very interesting. Obviously +4/+0 is way more than a / equipment would normally give; I do worry that on a first striker, say, the drawback would be very easy to avoid. And if anything, it feels a bit like a cop-out to let the third curse be removed by destroying the enchanted creature :)
