He will always be banned, but is still very good for Survivor.
I think you should sell him .
He won't get Unbanned for at least a long time . Maybe years.
And you should spend your clintz on a Freaks / Roots deck . with 33k that should buy you a Pretty good deck .
But really its up to u
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
If you currently have other strong cards, especially in Ulu Watu, keep him. You can construct a nice T2 Survivor deck with him that you can then use earn more clintz through T2 Survivor Mode. If not, then sell him for some nice cash for an ELO deck. I would start with Rescue.
Big 5 or not there is still talk of releasing perma banned cards when elo gets its next update.
I sell doubles mostly, but even 30k won't get you a great elo deck unless you get the right one the first time lol.
Maybe you'll have better luck than me : )
Tanaereva is a permanent banned in elo sell it if you don't have a good deck.. and if you have clintz make a better one..
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?
