I'm using this deck exactly, (except I have 5 SoGs and 3 Electrum HG) and I have to say it works fine. But I would like to say, that I am getting better results with HB than with FG. HB is almost a guaranteed mastery, only about 1 of out of every 4 has been a mastery, when I win. Also, when I lost, it's usually because I was too slow and had some bad draws and had to discard some cards. I really think you need to +1 steal, +1 quintessence.
There are probably more ways to make it better, but those are gaping holes (perhaps Owl's Eye +Flying Weapon?). Always keep a steal on hand, should be another tip of advice, as I narrowly won a game because my eternity got stolen, and luckily, steal was my 3rd to last card. If I had used it, I would have been dead.
One Quint for Oty, and one Quint for FFQ/Elf? That's a bit iffy. I think 3 quintessences to protect all three cards is the best.
I am ALWAYS running out of
, it's super annoying too.
Can we like get x3 marks like the FG?
Just my two cents.
