I started a little experiment about a month ago. But its over 馃檨
When Chaos packs dropped to $0.70 I started buying and opening them up. Card pack values were estimated at $0.93 (now up to $1.01). Seems like easy money 馃
I bought and opened 55 Chaos packs over about 2 weeks.
The best pack I opened had two golds - total value $2.58
Overall I spent $40.91 and got back $23.86 in cards 馃う I used full potions on all openings. Legendary dropped at 1.45%, Gold dropped at 4.36%
You can argue that if I keep opening I could hit a great card that will change everything. But I got 4 lengendary cards... 3 desert dragons (worth maybe $1.56 each) and 1 zyvax vuul (approx $1.29). With those cheap legendary cards out there its a crapshoot at best. No Mas.
