Man, playing 3 accounts, especially in the last days of the season takes hours since the matchmaking takes at least 2 mins per battle, as you're basically playing vs the same 5-10 people all day every day, and you also have to play a lot more battles as the skill gap at that level is non-existent. It's mostly about RNG - whose unit will go first in a battle where I placed my taunt at the back while my opponent placed in in the 2nd spot all other units equal. So, imagine being a "network" playing manually 15-20 accounts. I call BS on that. :) Especially if they actually win their battles since if you win 15 battles per day you are bound to end up at the top of the LB.
