Is it way too weird that this searches the stack?

Someone would have to respond to it with flash, and you'd have to have announced the stack before they did so (it being a sorcery) so barring Orrery shenanigans; it's probably not a problem.

I know that the situation would hardly ever come up, I just wondered if those situations should matter.

­Bribery is seen as an abusively good card. For one additional mana, you get several more options...
- targeting yourself (because you have a lot more control over the creatures you include in your own deck)
- dropping something in from the hand (a la Dramatic Entrance; say you planned on fetching out Emrakul but you accidentally drew it first--not a problem! You could also hit the opponent's hand, but that's almost a non-factor.)
- saving something from exile in a much more impactful way than Riftsweeper or Pull from Eternity ever could
- Dominate, with X = a really big number, the ability to bypass shroud, hexproof, and protection, and you don't lock in the choice until resolution so the opponent can't make it fizzle without getting rid of ALL of their guys
- Body Double
- and hey, if you're ever playing for ante and face the prospect of potentially losing a valuable creature, why not just plunk it straight onto the board? Kind of like Jeweled Bird, only the opponent doesn't even get to play for a card of modest value.

Clearly, this does naughty things, most of which I was aware of when I made it. Would these things be less bad/ more acceptable if it cost more to cast, or if it targeted only opponents?

Out of curiosity, can you pull things out of a set aside game and drag them into the subgame? Is the subgame in a different zone? Is that zone technically Exile? Can you Pull from Eternity a card in the main game and throw it in your opponent's graveyard during the sub-game?

Edit: Curious, I looked it up. 506.1a seems to infer that no, none of that applies, that the sub-game and the regular game do not 'see' each other in any way, and that a new set of zones is created for the sub-game. If you played Enter the Dungeon on me, however, I'd let you get away with it. ;)

Heehee. It's the reverse of my One-Way Ticket. SadisticMystic was the one to point out all the problems there too.

I think if this were 8 mana, all the listed issues wouldn't be problematic. It'd still be an awesome EDH card, but not as good as Bribery, where at 6 mana this is too much better than Bribery.

Perhaps 7 mana could be acceptable, but for right now I've put it at 8.
