Thanks for the help, everyone.

I burned my way to 50 (staying out of DD for a LONG time after this) last night and things finally clicked for me. Not to say I didn't waste cards, but I found that 90% of the time I found a solid use for anything I drew. Definitely liking AST a lot better now. Although I'm a bit baffled as to why Spread only works when in battle though. There was a few times I wanted to save a card only for the last trash mob to go down.

Hopefully the road from 50 to 60 will be just as fun as this was. Minus the DD grinding.
