I could have posted something more informative I guess.
I´ve been reading this forum before.
I used a recommended Aether stall/Fire bolt finisher when the Oracle predicted Morte. Nevertheless, it didn´t work. In some freak accident it worked on the FG I got after him.
Since then I was mainly trying this and the Flay´em deck, since I got neither Eternity needed for other decks nor Fahrenheit, which the Fire stall would need for example against a couple of FGs.(I took Pulverizer at Quest 7. Now I already have 3 Pulv, but still no Eternity).
I would be baffled if the recommended decks would have bad QI though.
Now the frustrating part is when you get the good hands against FGs you cannot beat with a certain deck. And no thank you, grinding AI3 is boring and pays less than low level PvP. The same decks work though^^
