The game doesn't strictly require a Xeno set, but for aesthetic purposes that was the spirit in which I designed the game. You can use two sets of the same type if you'd like.
Of course any excuse to buy another stash is a good one, right? :)

Mm. Sounds like you've put some work into this. It uses a Xeno set, huh?
Might have to buy yet another stash...
