It is a mini BP in which you get currency that is usable in this event only and you can only choose specific even items to spend it on. Unless you are paying to get more currency the stuff you can chose is very limited.
The 5$ pass gives you enough to get all but one of the skins. You have to drop 30 bucks for extra event tickets to have enough for all.
With the free pass you only get 120 tickets which is enough for 1 skin but not the skins that cost 160.
If I remember correctly, that bundle has 575 tickets right ? If yes, then you should be ok without spending the additional 5$. The event has 5 skins. 2 of these cost 160 each and the remaining cost 90 each so in total you need 590 tickets. You can get 575 from the bundle and the remaining from the free track
It’s the white coins and you don’t need the ticket pass because you get 120 tickets from free pass so in total you will have 695 tickets which are enough to buy out everything
Well you get 120 free tickets so if it were the gold coins, it would destroy the economy of the game and they might have gone bankrupt. That’s why it’s the white coins !

Jokes aside, this event is really stupid so don’t mind it too much.
If you just want the tracer skin then you might be able to get it for 1900 coins if you buy it from hero gallery. Usually the bundle items are available for individual purchase from hero gallery. Either way, have fun with your new stuff !
