hi again all.
reading around the forum, i've understood few errors, i guess.
first, that farm AI4 is not good, for me at least, because matches are soooo long, above all with a dim shield based deck. my doubts were origined because i can't farm enough ep.
now i'm using a mono death rush deck (drag, mumies, poison, gg) and i can play like 50 games/hour, with a very nice w/l ratio (idk scores now, but kinda 80%).
i'm getting money and cards, knowing more about game and reading decks.
so i guess this thread expired his utility (for me).
thanks everybody for replies!
