As I said on

He
ALWAYS play
Raubahn Aldynn, Shiva & Louisoix Leveilleur.
Last two cards are chosen randomly with an equal chance between Nanamo Ul Namo, Alphinaud & Alisaie, Thancred and Ifrit.
I'm trying to find a tactic to beat him consistently, currently I can't beat him more than 33% of the time, especially if I'm the one to start.
Edit: Went 8 wins - 11 draws - 3 defeats (22 games in the 6am-11am Eorzean Time window) with this deck:
If you're first to go, play Bahamut bottom right, other cards top right. Then pray to Chaos RNGesus
Went 8 - 6 - 5 and finally got it (along with 7 Ifrit Cards and 2 Alphinaud & Alisaie cards)
Hopefully that will help me in those Random games vs Rowena & that south shroud dude.
