So, basically
Parallel Universe for permanents that could create mass copies of itself due to it being the active ability of a permanent? Don't know, really. This card may force a duo, but I can't tell really how it works. Even if permanents are less important than creatures(unless we're talking direct quanta generation), and also a little weaker, making mass copies of, say,
Bone Wall would not be nice, at least for me. The upgraded version is somewhat splashable, making it a little hard to reckon with if put in the correct combos. Let's assume:
Armoury,
Bone Wall,
Graveyard,
Soul Catcher,
Schrödinger's Cat,
Heavy Armor,
Mark of Fire,
Amethyst Tower,
Earth Pendulum, I would be a little scared, really. It's pretty powerful in a sense. And maybe some other
card that is not too costly. And maybe some
quanta for opponent's permanents.
In the end, this is the cards in-game this could be related with:
Parallel Universe, but for permanents.
Steal, but without any losses for the opponent.
Mindgate, but without paying the quanta cost for the card copied. This one I'm particularly concerned.
Mitosis, but starting on the board with the ability itself and being of a different quanta cost and also cheaper.
Some balancing would be nice, starting by the cost of the card to make it a little less splashable or to compensate for being an ability instead of a spell. restricting the targeting to opponent only could also be an option. But it still is pretty similar to
Mindgate, in the copycat sense, of course. The notes section tells me it is intended to only be able to target the opponent, but as it isn't implied on the card as well, I'm assuming it is ANY permanent.
