How you earn points from duels (work in progress):
Win: 40pts
Win against opponent at least one level higher than you: +7 bonus (this is per duel)
Win for a match: +1 bonus (only if opponent is a higher level than you)
Win against opponent at least 4 levels higher than you: +1 bonus (only 1 bonus per duel/match)
==================================
Loss against lower level: -16pts (still investigating…)
Loss against same level: -1pt (per duel, still investigating…)
Loss against 1-3 levels higher than you: -1 (per match)
Loss against 4 levels higher than you: 0 (per match)
Examples:
So, for instance if you’re level 17 and you win a match against a level 21, here is how the score is compiled:
2x(40+7)+1+1 = 96 pts (if the duel was against a level 18,19, or 20 it would be 95 pts instead of 96)
If you just duel a single against someone who is one level higher than you and you win, you get 47 points (40 plus the 7 bonus points; it would be 48 if your opponent were 4 levels higher than you are)
If you duel against someone the same level as you are lower and you win the match, it’s only 80 points total as you do not get the bonuses.
The only exception to this is a single win against opponent at least 4 levels lower than you: 32pts, but winning a match will still net you 80 (I’m still researching it as it is a bit strange, but I have confirmed it does happen)

About LV from my experience It’s seem like High Level Player have more chance to get rare/good cards from opening pack and if you make a same deck but one with high Level one with low level It seem like High LV Player have more chance to get a better hand when start (I’m not sure about it).
