Alright! Getting some Mashup: the Gathering done! First up, now that the skeleton is in place, I need to do some hole filling. It won't be a proper Magic set if there are, for example, no Shatter effects, or counterspells.

­Demystify effects have yet to pop up, so I take that and... let's see... random generator gives me Savaen Elves? That's... that's awfully specific...

After a little while, I gave up, and was forced to think about this the entire ride home. I had an undending litany of stupid cards run through my head, including this one:

­
Instant
Destroy target aura you do not control on a land you control. Gain 50 life. ­

The problem here is that Savaen Elves asks for you to make such a specific choice... but I need a common disenchantment for the set to make sense, and it needs to hit just about everything.

I think this one works, though, and keeps the spirit of Savaen Elves alive. It permanently protects a land from enchantments... you know... if that was needed. Most of the time, though, it's going to operate a Demystify seal, that kind of hangs out on a land. That idea is kind of cool... seals that enchant lands. I mean, the lands are almost guaranteed to be out there and sticking around... why not give them bonus little abilities?

Hm. To me, the obvious mash-up would be "G. 1/1. GG, T: Destroy target enchantment." But that's much too general. I'm not sure if it could be turned into a common.

Yeah, obviously, I couldn't print that card at common. I did think of this:

­
Artifact Creature
When ~ enters the battlefield, destroy target enchantment.
­, : Destroy target aura enchanting an artifact.
1/1

But it kind of failed the "Small enchantment destroying card", and the "feels like an common to me" test.

Bumped by Kobold Rainmaker. Filling holes, then bumping the hole filler with a different hole filler is a very strange process...
