For the price that will be bad

I guess Revival Gacha is meant to be always used with Card Reveal (at least, shen you spend your first Revival Gacha Tickets Bundle and get several cards, so duplicates could start showing up). But yes, eventually it will come to the situation when al 6 cards in the "hand" will be duplicates of the ones you already have. And pray that they will give you at least SR 1 Wild Cards when you get those cards to lvl 100. Because they might give you Pero, like Ngacha or Exploration/GHQ etc, lol.
So, no way. Even though i'm an obessed collector, i'll rather discard my habit instead of throwing cash at those asshats. But meh, i wouldn't buy those tickets even if the cards won't show up again once obtained.
