Oooh I really like this, just hoping it isn't too strong with a board full of Emulate creatures. Would keep an eye on this during playtesting.

Seems very similar to Whiplash, except this can also shoot players with any spare emulations you have left. Similar concerns to Whiplash apply.

Definitely a card that needs to be tested. I see this being a huge role player in emulate decks as a win condition or a premium removal spell.

Like Whiplash, I think demoting it to sorcery speed should help curb it's power, since maximizing it would mean using a player's entire turn, as well as eliminating it's applications as a combat trick.

I'd like to point out though that these cards only seem powerful due to context. Each is analogous to another one mana spell (Disfigure and Shock respectively), neither of which are all that great to begin with. This cycle is based on Banishing Knack, which provides an effect more powerful than the standard (it hits permanents unlike most one mana bounce effects), even though it also appeared in a set that could abuse it (via shadowmoor's untap mechanic.) If these cards end up being too powerful, it's probably due to an error in the costing of the Emulate mechanic as a whole rather than these cards individually.

That's fair. I remember Banishing Knack turned out to be pretty hard to get much value out of. I agree you want some strong pulls towards an emulate deck.
