Mashup of Cache Raiders and Land Equilibrium.

Again, the cards went together quite well. Except I decided that the taxing+bounce was more white than blue.

I wasn't sure exactly what combination to go with -- bounce permanents? Or a choice or permanent type? Or each permanent type? But "creature" was simplest and most interesting.

I'm not sure of the cost. It's probably most useful for creatureless control decks to slow down their opponent; it's quite expensive, but it holds your opponent back a lot if they have to get two creatures to stick before they can start attacking. Would it be too annoying?

And it might be useful to reset your own combo or something. It's a lot less attractive to use on yourself when it's not a decent-sized creature itself, but I decided the simpler version was better.

Yes, I can see this. It's a nice defensive card; quite white - and I'm sure people can find tricksy things to do with it when they have creatures they want to bounce.

Four mana feels about right to me. It's more annoying than, eg, Ghostly Prison but less annoying than a wrath.

Reminds me of Sunken Hope a bit. This does have the white balancing thing, though.

I once tried to combine Sunken Hope with Mistbind Clique, but it wasn't fast enough.

Hmm. I find it interesting that you chose to make this an enchantment over a creature. I can see your reasoning behind making it an enchantment, but like this, I would say that the best place to stick this card is in a deck with zero creatures. Combined with, say, Aether Flash, you've pretty much locked some opponents out of the game.
