As stated above, Random needs a good fixing if they pretend us to have a decent chance against NPCs like Rowena and Landanel. By all the gods of RNG, I was blessed that by winning Rowena like a total of 6 times out of... 80 matches or so... I got 2 Gerolts and 1 Luis. I only got Titan from Landanel so far out of the wins I got to him. His deck is just enfuriating unless you have probably already 60 cards, but if you're trying to get the brothers and Odin/Titan from him, chances is you have not that many, and all his cards will just flip your deck, no matter what you play, unless he goes batshit stupid in 1 match out of 50 and you had the luck of your life with your own cards.
