There arent as much commons now, we should have more, here are my ideas:
Flare (Wind, Flame)
Primal Phoenix (Primal, Wind, Flame)
Coldwar (Ice, War)
Frostwing (Ice, Wind)
Zorgo (Metal, War)
Soulfly (Wind, War)

Please? it would just mean another way to spend our money on things we cannot use outside of collections.

Outside of that aspect, your suggestions are very well thought.
