I'm not sure if this is a very original idea, but here goes:
Should the "Other" category be developed into a full-fledged element with its own spells, creatures, rare(s), shard (excluding the Shards corresponding to the other elements), etc.?
Here is an idea for the rare weapon of the "Other" element.
Weapon (Rare)
Cost: 5
Damage: 4
Animated Stats: 4/4
Active Ability: Blacksmith (This weapon turns into a random rare weapon)
Passive Ability: NONE
I think the "Other" creatures should have the ability to change colors, and there should be "Other" cards that benefit them if they are a certain colors. This will obviously result in more "Other" cards than any other.
Suggestions, community and Mr. Sequoia?
