Good for you then.
Personally I didn't have too much trouble against six sams in the last months since I have been playing a near 0 spell/trap deck at some point. But for beginners 1 enemy Shien = bad game.
less than i needed with my shiranui deck...i had little success with shiranui ,so i was like frick it,i build a deck where i can summon 2 shi ens or at least 1 with some protection.And in less than 30 wins i hit kog.
