He always does this, Every deck is a KoG 10000000 win 0 lose deck. Anyway, for reaching KoG you have 2 options. Make a T1 or T2 meta deck or the second option wich is worked for me more than once. Try to make a counter deck. One of my proudest kog when everyone used Six Samurai decks back then and Shien ofc. I made a Yubel deck with 99% monster effects. I destroyed them completely.
