Can we just accept that some cards are always going to be better than others? SoPa and SoFre are OP, regardless of which teams think they can use them. Doesn't mean they should be banned outright. We have market prices for a reason.
I like that JCJ is trying to show us SoPa can be used by just about anyone, some of those decks are pretty creative, but the point about that making it balanced for War simply doesn't hold water. If anything, that fact that any team can use such a powerful card makes it MORE centralising to the meta, not less. Making shards like this cheaper is a bad idea.
Even so, I'm still of the stance that no legitimate card should be banned from the entirety of War. Appropriate market pricings and better preparation from particularly vulnerable elements (looking at you
) will help.
