So my friend has been telling me about Contest of Champions for a couple months now, and I never really bothered to try it out. Seeing as how I had a day off I call him up to tell him I downloaded the game. He swings by and gives me a couple tips before I start playing. Never sell heroes, don't buy crystals, save units for masteries, get Parry and Dexterity. He also tells me to not get too frustrated when I don't pull good heroes.
I guess I got pretty lucky with getting a 4 star from a premium crystal after beating Act 1. He shows me the Intel quests so I did some of those and got some shards. Three crystals back to back to back and I get these guys..
