Yo folks, I've been playing this game for a while now, although my level is only 37...probably because I don't play many games in a single session.

I don't think I like the upcoming changes to the game though. It seems that the current collection of cards will only be available for the "open" format, the so-called legacy format for this game. I guess this isn't new, but the fact that the current expansions will only be purchasable with seals once the changes kick in, and that seals are almost only obtainable through money, means that no new players would be playing this legacy format. If that happens, the legacy format will slowly die out, and all our current cards will be rendered useless

At least this is what I gathered from the Ubi forums...
