wow, Six Sam is not on a single list. Anyway, they got lots of nerfs, but you can still make them work. I am using Balance skill:
1x Kizaru
1x Grandmaster of the 6sam
3x Kizan
3x Fuma
1x spell of choice
2x World Legacy Clash
3x 6sam United
1x Return of 6sam
2-3x trap of choice
2-3x Dual Wield
extra: synchro monsters of choice
yes, I do not use Dojo because it just started to suck with all the nerfs. I get Shi En out on a regular basis.
WLC+DW is just so strong and makes this version so fun to use. It is not as strong as its previous version, but still good and fun.
Try it out.
actually I can see the reason behind his strategy. Shien is not strong enough on its own anymore so it is actually better to have six sams on a field with dual wield and wlc than useless shien on its own
3 Dual Wield + 1 Enishi is usually good enough to get rid off your opponents monsters and protect Shi En. And Rihan is also a good choice to banish them and a great Floodgate counter. It's also much better against Yubel decks.
And make sure to run at least 1 Level 9 Synchro to counter Lava Golem.
If you aren't going to use Dojo or enishi then why not go use the level 2 tuner with Kageki and asceticism? It puts out Shi En consistently allows you to use legacy clash.
