Oooooo! Unlimited? You went straight into the lions' den, lol. Some available cards/players are definitely better than what's in PNO. Plus, you have to take in consideration that you create your own roster, so I'm going to assume that you put together the best team you could.
To my understanding and from my experience last year, this is the best time to play Unlimited, because you don't have to worry about OP cards like Yao Ming who can shoot 3's. Over time, Unlimited will start to become "unrealistic" while Limited will stay mostly grounded throughout the year due to the roster restrictions.
I'm curious. What was your squad, since you officially dabbled in the mode? Currently, I have....
Amy Steph Curry (still can't shoot with him, lol)
Ruby MJ
Amy Xavier
Amy Horace Grant
Diamond DeAndre Jordan
Ruby Morat
Amy Fred Jones
Ruby Butler
Diamond Kukco
Amy Tyson Chandler
It'll probably be about November before they release enough cards for me to create my Pacers-themed squad.
