I like this bet... I'm leaning toward @rentmoney taking this home though.
Assuming the "earn 50 packs" in @aggroed's "wager" is referring to season end rewards only, there's still a bit of a challenge.
The straightest path here being to create 10 accounts and getting each account to Silver 2 for the season end reward of 5 booster packs per account.
With 11 days left until season end, each account will earn 11 booster packs each from the daily quests. With some luck on obtaining summoners and a few good monster cards, you should be able to combine/trade cards between the 10 accounts, while being mindful of cooldowns.
The only real challenge is getting each account to Silver 2.
Getting into Silver will be easy... but going from Silver 3 to 2... some RNG, team formation luck and enemies fleeing is what you need, @rentmoney!
Good luck!! :D
Daily rewards count towards the bet.
Ummm.. cakewalk! LOL
