If Champion's Vigilance isn't banned soon Konami is a bunch of morons. That card is so unhealthy for the game at this point in time and will cause players to quit soon. It isn't just the best card in the game, its on such another level compared to other cards that it ruins the game entirely.
I wouldn't say it's being salty, I have the card and still think it should banned. It's on a league of it's own especially with 3SD, which will be nerfed in the future. This card fits well in 2 of the big meta decks and is almost a guarantee win if you draw it with your opening hand, the only way to "beat the card" is by getting lucky that they don't draw it.
The card itself isn't terribly broken, 3SD is what made it broken as hell. I run gale lizard too counter, but an only run one, Plus in a 3sd deck all that is going to happen is there gonna use a berry and put out another beater. If you play against a 3sd deck that draws a Vigilance and a way to get a bug normal beater it's gg 9/10 times
