There is a pretty steep learning curve if you wish to play ranked matches but there is also a ranked tier system to help match you with players who have a similar rank
Just tapping to make a Treasure token over and over again would be pretty valuable, so you can just use this End of Your Foe's turn to make a Prism, untap, and draw and then cast your normal things possibly accelerated by a Prism sacrifice
This type of deck loves a little self-mill to get it going, while also having plenty of ramp to be able to recast those cards
Those counters don't do much while the token has its front face up, but they do a great job of keeping the Phyrexian artifact creature alive once it transforms
I know what my baselines for my search are with this info
