Initially I had it worded to give you the unchosen options from any Discover, but the feedback I got in the discussion pointed out that it'd be OP if you could always pay (3) to get all of the options of your last Discover, plus a body. I've changed it to only trigger off your opponent's last Discover. If your opponent runs no Discover cards this is a subpar 3-Drop. Even if they do, it's now usually a gamble for what you'll get.

It says each other Pogo-Hopper, when you play your first one, you haven't played any other, so it will be a 1-1 first, and then 3-3, 5-5 etc.
