I am well aware of PJ and everything splinterlands... I think winning a mystery potion lottery (which a small percentage partake in) and introducing controversially powerful cards that have high value vs. having the regular game cards in super-rare form is a no brainer. The cards are not more powerful, they just are a different colour and perhaps hold a different DEC bonus.
I love the game, I love the way it is at the moment, I appreciate the struggles of trying to keep everyone happy and the risk of making people mad.... but I do think that the upside on this one greatly outweighs the downside.
