Either way, I'm completely certain the event card is far better than the others last war that gave all cards upgrades.
I disagree. The problem with that old card was not the concept, but the fact that the number of upped cards wasn't limited to.. say 6 cards. I like the concept behind those cards because they totally changed the deckbuilding for that round when all teams try to either use
cards as much as possible, or try to build counters for
decks, knowing that other teams will have upped
cards. It's basically putting one element to the center stage for one round.
Issue with cards like Stroke of Luck is that they benefit the few teams that got lucky, while for other teams it's like there was no Event Card played at all. Random lucky-based cards like that, without any unique effect, are boring. Like I said before, Stroke of Luck doesn't kill this round or the event, but we have to identify a bad card when we see it, and not use it again.
