My opinion to most of the shards: They are totally OP for an "Other" card.
Rest of my opinions (which guided my "worthy" on first page) :
- They are too dependant on their element
- They don't fit their element
- They have an unclear/bad/mispelled mechanism
I mostly agree.
Anyway, i recognize that making a balanced card with clear mechanism and a fitting flavor, that also gives a bonus to an element without being too much element-driven is an hard task.
Everyone made his best, or maybe just give a try, but often cards need feedbacks from the community to improve machanics/balancing/flavor. But this is a competition, so there is no feedback. It's just you and the card.
