That's not just a counter, that's a nail in the coffin for Lost World. They may as well just not print Lost World.I'm hoping for a hard counter to Lost World (assuming it is printed in English at all).
Something like this:
Locked Gym
Stadium
[picture of of a Gym door with a big lock and a "Be back later" note on it.]
Players may not play any Stadium cards.
Return Locked Gym to it's owner's hand whenever it would be placed into the discard pile.
The Gym Leader is out, please come back later.
A counter would be good, but not THAT good of a counter. I just want a somewhat more limited way to get things back from the Lost Zone. It should be more limited that discard recovery, but still somewhat helpful. A coming into play power, maybe?
