actually, he isnt. there are going to be changes to the ELO mode within a few months i asume according to euzebes message. that meaning anything can happen including letting the big 5 back
I'd probably sell him and get some of those cards you've always wanted cause he's gonna be banned for a while.
Depending on how serious you are about the game, spend money on new blood packs the day new releases come, then sell the new recuits right away, wait 2-4 weeks you can buy them back at 1/4 of the price you sold them for, use the profit to buy the cards you want for a good deck. Who knows what will happen, will you even be playing in a few months?
