You will see a mix of classic FFVII moments and modern FFVII visuals in the deck, but generally, the product is intended to follow the original games story
And while we have only had a single batch of official WOE spoilers and around 20 cards leaked, some cards will do very well in Commander

Maybe an even more shocking stat is that, taking into account the low value of the rest of the set, most of the time when you open an Invocation , you'll still end up losing value, or at the very best breaking even
You could usually break it way too late in the game for it to matter
