I thought I'd document opening some Chaos Packs, so I opened up 5 Chaos Packs, with potions and got the following cards --
I did better than average, I think. For each pack, I'm guaranteed one rare card. But in total, I pulled 7 rares and 1 epic, including one summoner! No Gold Foils, this time, but I'm pretty happy with getting a summoner and Grund! I've been looking for Grund so much that I was thinking of buying the card, but no need to now!!
