Not really, even for 30d MS, it's not worth :')
I see 2 cases to use that Slot Machine System :
- For Reroll ticket because you can have it only with PVP Coins, so it's a limited resource. 150 PVP Coins for 1 Reroll ticket to try to reroll nature, it's a lot! So, the fact you can try to have Reroll ticket with pokedollars makes it worth ;)
- To sync Porygon, the only unsyncable PKM until now.
For the rest: MS, BMS, it's not worth, it's cheaper to go on trade chat :y:
Edit: For Possible Shiny, depends what is the chance of Shiny, and for what PKM. Because if it's 1/1000 to have Shiny Caterpie, it seems not worth :')
you can buy 30 days ms, 15 days ms, bms with lower than 80k?
I want to buy that too
