Yeah, as long as they think Survival's End decks are not majorly disrupting the sales, it won't get hit.
The other anon is also correct, Konami did the emergency ban because it was unbalanced - remember that it was at the time when the game is still new and they are still trying to attract players and keep them in the game. Unbalanced deck like Bamboo FTK would make them go away.
Stuck in 2017? Not really. Of course a lot of people still remember bamboo deck, it was notable for being the first and only deck so far to be emergency banned. It was the only example of its kind, and has nothing to do with "stuck in the past" at all.
5 6 months?? Lmaaao keep dreaming. Koaki got hit in 3 months,and you think this f2p broken deck will not get hit for about 5 6 months?? LOL they'll nerf the 🔥 out of this deck.
