Guys I used to farm him with yubel, ojama and fisherman but none of these decks where consistent and a 8k win gave me just crap so I got fed up and auto dueled him with the assessment point booster and voila I acquired all the drops
Infernity Break and Zero Max can really mess your setup using this deck, though it's really occasional. I've won a lot of times using Unhappy Girl deck but I lose couple of times due to brick and above.
there's still time. keep on trying guys. I got 2 of my inferno from farming level 30 actually, using the same deck. you might want to try that if you didnt farm lvl30 before.
and yes. to me inferno was the hardest one to get.
Besides, MVP is 3x WOD, I did not favor floodgate that much in this deck. I only want 1 of his monsters face down, becus I need 2 face up for the final blow. For some unknown reasons, he keeps on switching his 2 0 ATK monsters to ATK/DEF position.
