Experience

Experience I made a few accounts to gain experience.
Well, the result: no tactics matter, the system will favor a given person for some reason in each game: one acc. was completely successful, the others suck.
The rolls, the development card deals are all... no one needs to bother themselves, who will throw the template texts here: the statistics and tactics and blah blah blah....
I didn't start in the past few days..

If your theory is correct you can continue to play with your lucky account and you will easily reach ELO top#1.

In fact you will realize that your "lucky" account will face unlucky streaks in the future and you "unlucky" accounts will face lucky streaks. This is just part of true randomness. You cannot predict, however, when you will have the lucky streaks and how long they will last (positive and negative streaks usually last much longer as our human brain expects - alternating sequences of luck are very rare).
