I really hope they bring Venser back from the dead somehow... and I hope they don't do it by turning him into a Phyrexian.

A planeswalker with Flash would be freaking awesome :)

Few things I'm undecided on with this guy: whether or not 2UU would be fair (I'm guessing it would be, but a little pushed), and whether or not to make his ultimate -9. I'm thinking at 3UU, -7 is fine because even though the opponent only gets 1 turn to interact, his ultimate isn't that powerful for a 5CC planeswalker. At 2UU, it becomes a bit more debatable.

Also, the whole tapping business is because of a rules thing. If I only make his abilities instant, then you would be able to use him on your turn AND your opponents' turns because you can use planeswalker abilities "once per turn". So, the cleanest way I could think of to word being only being able to use his abilities once every "turn cycle" was to use the tapping mechanism. And also, it leaves a cute loophole for the aspiring deck-builder if they want to try untapping him to get uses out of him on their opponents' turns somehow.

Yeah, after some more thought, I think 2UU would be too good, considering his ability to reset planeswalkers and other counter-based permanents. At 3UU I think he'll still be fine, but not too unfair.

Double Boomerang-ish alone is worth the . You wouldn't even be able to attack Jace in between both those activations. Just play Jace at end of opponent's turn... when you would normally cast your bounce... then activate him again on your turn. Dangerously good, when you consider that this can bounce an attacking creature every other turn... you know, the turn after summoning sickness is dealt with...

Really, I think this card needs to be tested. I suspect that this package of abilities is a 6cc card, but I'd hate to it cost that.

But no, double Boomerang for isn't worth it, considering how much constructed play Into the Void sees. So, if you think about it, this is JTMS, with a roughly-equivalent [+2] ability, no Brainstorm ability, and a slightly better version of his [-1] but it's [-2] instead. His ultimate is worse, but much lower cost. His only main advantages over JTMS is his ability to flash into play, thus getting an extra activation (and thus potentially much more starting loyalty) before he can be interacted with, and the ability to wait till their turn before bouncing. The difference of costing more, making the bounce [-2], and no card advantage makes a reasonable cost, I think. But you're right, there's no substitute for playtesting. :)

As an aside, the [0] ability on JTMS is by far the ability that makes him good, not the [-1]. If JTMS was printed as he is except missing the [0], he would not be constructed playable.

In summary, to be honest, I'm not sure this would ever see constructed if it's costed at , but it's much safer there. If it were then I would be very surprised if it didn't see any play, considering at worst it's basically Into the Roil with mandatory kicker, but instead of drawing a card, you put a 2-loyalty planeswalker into play. I also don't think it would dominate any formats, it'd just be pretty good.

The comparison with Into the Void is interesting. I didn't even know the card exists. Still, it isn't perfect, since Into the Void is a Sorcery, only hits creatures, and can't spread it out over multiple turns.

But, yeah, same here. Planeswalkers are real nuts to crack, even when they come out well designed, like this one here. One of these days, maybe I'll grab every Planeswalker on this sight and give them a spin, just so people can get some feedback on whether their card is too little/too much. ;)
