Unfortunate that this will only ever be used in a Monoaether for Dims. The positive is that EA Dims isn't such a strong deck that it can't be a mono, so it gets a bit of a buff.
Regardless, I think you need to find a way to differentiate it from EA in some way. While 3 turn duration does that, it also makes it useless outside of Dims, so I'd find some other way. Preventing x (3 seems good) amount of PC uses and costing 1 less would be a simple way to do so, though unexciting.
