For Challenge # 054. Jack's right... it's too easy to exile a pile of cards and take advantage of that. I aimed to instead focus on whether you had an odd or even number of cards in your exile zone. You can still abuse this card with instant speeed exiling tricks, but you'd only get to switch back and forth between his two modes.

I like the even/odd concept. I tried to think of something similar but it didn't quite work.

I wonder if we can make the two different modes slightly more interesting though. I'm trying to think of something where switching might inherently be useful, but I can't quite think of anything.

Also, why w/b? To me it mostly feels green, although I think it could be a g/x hybrid

For exiling cards off the top of your library, mostly. I know that drawbacks like that commonly appear on any color... but I figured that doesn't mean that white or black shouldn't be used to represent the drawback. Red's there because of the random thing, though, I admit, this probably could have been any color combination at that rate. I could even see this costing and being some sort of wacky tidal Leviathan.

Blue gets both the exile bit, and the "Every other turn bit" (phasing, tidal) so pure blue makes sense to me.

(Blue also gets large overcosted creatures with downsides and drawbacks...)

This is a very clever way to care about the number of exiled cards without scaling madly with Arc-Slogger etc.

(Aww... and now I'm getting nostalgic for my/qqzm's old absurd Arc-Slogger/Synod Sanctum/March of the Machines/Quicksilver Elemental deck. It didn't do anything 9 games out of 10, but the occasional game where it plumped your deck onto the table was so worth it. Curse you, linked abilities rules.)
