If you click info on the event map it says on 24th one 89 master that requires the 3 promo 87s. And then it says the 89 can be boosted to 91, presumably that’s with the keys and probably some more stuff like a bunch of player cards, because this dev team is all about more stuffSounds like just one 91 Grandmaster, different than the rest of the cards/ players
Easy.. no promo is not grindable since s4. Even casual grinding can give u enough stuff to sell to buy an 87 of the ahare all 3 masters really grindable? havent bothered with this promo as it seems cant even grind one 87 master let alone all 3. am I missing something here?
