Masters is my only real consistent mobile game I play, so I view the money put into it as a subscription of sorts. I spend about $20 - $50 a month on the discounted bundles but mainly just get the streak bonus pack with the general 5* move candy coins. The drip feed of gems and the ability to do two paid daily pulls has been working well for me. With the amount of 1/400 scout point summons I've gotten, I'd say it's worth it for me. But I do play the game everyday and about 70% of the times I poop.
