I think since there is a moon damage wand, there should be sun and star ones just for the heck of it.
Solar staff: gives 5 sunstrike cards (130 sun damage)
Cosmic club: give 5 starfire cards (130 star damage)
New healing wands would be great to. They made the ones that give minor blessing, which I think was a great idea. I think KI could take advantage of this and make new, better, and stronger healing wands that can give new cards such as just simply "blessing" cards that heal 80, major blessings for 95 super blessings for 110 and mega blessings for 130.
