Ok, one more clarification on rules.
round 1: Fire/Water with Aether Mark
round 2: Aether/Time with Aether Mark
round 3: Entropy/Gravity with Aether Mark
Is that legal? IE can I use the same mark but different decks in all 3?
Also, what about:
round 1: Fire/Water with Aether Mark
round 2: Aether/Time with Aether Mark
round 3: Fire/Water with Aether Mark (same as first deck, but I did change elements after second match)
*note, this is hypothetical, don't question the logic of each combo.
