Consistently pulled draws and wins. I'd chalk losses up to RNG with this ruleset. Plus Side of playing Lewna, all her card drops sell for 1500 MGP.

Was missing a card from soraya's recommended deck. I added Behemoth to my deck.

Total Games Played : 49
W:27
L:6
D: 33
87% W/D rate and a 55% W chance.

Obtained 3 Onion Knight, 2 Terra Branford and 1 Bartz Klauser card(s)

I think replacing behemoth with a card that has a 1 in the left spot and similar high stats in the up and right positions would result in more wins.
