Welcome to the roughly-10day-intervall-featured rules! These 10 days (well, week hopefully):
Trials stuff: Both players choose an element. In each deck at least 50% of the cards need to come from those 2 elements (note that your opponent may use your chosen element for that purpose as well).
And an alternative bonus rule to make up for the late post:
Red and blue: You can use red or blue decks (you may also play a red deck after a blue one and vice versa). Red decks may contain any
![Fire :fire](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/fire18x18.png)
and
![Entropy :entropy](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/entropy18x18.png)
cards except firebolt and discord. Blue decks can contain any
![Water :water](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/water18x18.png)
and
![Air :air](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/air18x18.png)
cards except Shard of Patience and Owl's Eye. 12 upgrades, other cards allowed (but not from other elements, just the colorless ones), mark can be chosen freely.
The latter was a rejected tourney idea; if you try it out please remind me why it was rejected (it doesn't seem so bad).
