What about trading no cards for no cards?

possible but ultimately useless

Trading becomes too powerful if one player can agree to dump all of their cards into an accomplice’s hand, for free, repeatedly. I assumed this was a declare-then-swap mechanic (rather than a “wizards may give cards to each other at any time, sort it out yourselves”) to avoid exactly that.

Without wanting to peanut too hard, pooling stuff into another person to make them win is admittedly quite common.

Although I believe we all mostly already know that from experience, except the newer players (hello and welcome to you guys btw!).

Yep, picking and pooling doesn’t really make sense for this game.

I have a similar idea about using Thaum as currency.
