I've been trying to build a deck for this card game but I'm having a bit of trouble with it. I'm still under 30 cards so getting to that point is my goal atm.

Which brings us to my question: what's the drop rate in the packs you can buy from the vendor? I've bought like 10 silver packs and all I ever get is the Slyph card. Do some cards just drop more often (coughslyphcough) than others or do I just have incredibly terrible RNG luck?

It feels like I'm wasting my time and coins on the silver packs. =/
