Any person who can think properly will understand this:
Given that fact that FG has 200hp, more than 60cards in deck, can draw 2 cards/gain 3 quantums per turn, you can not seriously come up with a deck that can beat a god w/o a bit of luck involved. Take miracle for example, everyone thinks he's the easiest of the gods, try taking him on when he got 4 dragons out in 3rd turn, and for the next few turns all you got was nothing but supernovas, pillars and a funny looking Oty out waiting to eat that dragon with nothing in your draw to decrease that 12hp to less than 5.
All we can do is to make our FG deck be able to counter-attack as many kind of offence the FGs offer to us, by doing that we will surely increase our percentage to defeat the FGs, but not necessarily guarantee 100% complete dominance.
However Yaladilae, if you post your deck out and ask for comments, surely you would expect some reply like that (other's may like your deck as well), you just got to take the good with the bad, i would say look at their reply, if their reply is really childish and they dont know what they're talking about, don't bother with replying them; sooner or later they will find that out for themselves.
