But to my understanding you would get a higher reward against unoriginal decks, unless I missed some exposition.
Absolutely! The reward (noted R whith NR being the reward we have now) for beating a deck played by the AI would be
R(human) = NR(human) / H whereas if said deck beats you the reward for its owner would be
R(AI) = NR(AI) x H.
For a deck with a high handicap (Firestall, Ghostmare, Immorush) => 0.1 < H < 1 then R(human) > NR(human) and R(AI) < NR(AI)
For a deck with a low handicap (Eggosis, Franctantlion, ProtecDissShield) => 1 < H < 2 then R(human) < NR(human) and R(AI) > NR(AI)
It is the logical behaviour of a handicap system. A deck with a high handicap (0.1 < H < 1) is supposed to be better. Therefore beating it should give you more. On the other hand it beating you will reward less.
[...] the handicap on the firestalls would mean they need more wins to gain rank...which is easy for a firestall.
Maybe but a loss would cost them so much that they would be kicked out way faster.
Lets call GW and GL the gain in rating for a win or a loss respectively and NGW and NGL the equivalent that we have now:
GW = NGW x H and
GL = NGL / H I think in platinum NGW = 10 and NGL = -45 => ratio(-NGL/NGW) = 4.5
For a deck with a high handicap (Firestall, Ghostmare, Immorush) => 0.1 < H < 1 then GW < NGW (for H = 0.5 we obtain GW = 5) and GL > NGL (for H = 0.5 we obtain GL = -90) => ratio(-GL/GW) = 18
For a deck with a low handicap (Eggosis, Franctantlion, ProtecDissShield) => 1 < H < 2 then GW > NGW (for H = 1.5 we obtain RW = 15) and GL < NGL (for H = 1.5 we obtain GL = -30) => ratio(-GL/GW) = 2
Bragging Rights vs Electrum.
No with this system a deck with a high handicap (0.1 < H < 1) will earn less electrum
and less rating for the same amount of win.
