I have 3 things to say to this:
1. No elements is BAD. It's god good cards for different situations. Saying one element is better than another is biased, because they will all be balanced in the future.
2. Some cards are a bit worse in mono, but that's just because they need the synergy. That makes them strong.
3. I'm abstaining from this poll, but personally, if it was there, maybe Other. xD
Although I love the shards and quantum towers build the framework for my rainbow, I wonder what would happen if we actually gave them some creatures.
I voted darkness as the worst,
as i base internet games on PVP,,
and assuming this vote means mono decks,
yeah, it sucks.
Why diss on light, so hard?
Its amazing with gold dragons and bless with heal etc.
you obviously haven't tried a mono darkness denial and/ or a vampire deck.
