EFFECTIVE is the key. I won't go into details, but think about all the good bow cards, nearly all of them has a nice duo possibility.
I'm merely venting my frustration that since I entered Elements' competitive PvP bows always get screwed in the Trials.
Either ian banning Nova for me or the rules are way too restrictive. At the same time I look back at earlier Trials, those were Nova heaven.
ps: you can still use more than 1 bows, right? They just don't get the rainbow treatment talking about used elements, if I understand correctly.
