conspiracy 1 booster box MTG (36ct) (CNS) : Toys & Games if you can keep it Conspiracy Booster Pack

Not the greatest deal ever, but not embarrassingly bad either

Chromatic Lantern followed a similar path where it was actually needed by players of all five decks but only printed in one of them, and the card has since increased in price greatly

Though players can still respond at instant speed before this goes off, the card seems like it'll still be effective in commander to shut down a high impact turn

Harness the advanced technology of the Sothera system as forces vie for cosmic power

Save and reset after that, and repeat to see if he'll offer a new trade (he only does 3 and I think they have the same required cards as the original game)

It would also grant them an additional 500 attack points after being played
