How would you describe the gameplay? I'm getting a sort of two player combat card game vibe (similar to magic or star realms). I might be totally off base though.

In case you're unaware of it, the game design forums on board game geek have a lot of resources for game designers: https://boardgamegeek.com/thread/933849/designers-resources-list.

I use illustrator for most of my card design, but a lot of people use nanDeck for card layout and such. May be worth checking it out: http://www.nand.it/nandeck/.

I'm excited to follow your progress.
