So, now I understand why it is so difficult to create appropriate Light cards.
I voted for only one: Solmancer. Particularly with Seraph around now too, it is a nice nudge to encourage more Light/Fire duos. It has obvious synergy with Rage Potion which I like, though as it is the upgraded version gets less defence (IMO not what the card ought to be about).
Now I want to think of Light Cards!
