I often win with this, you just need go 3rd or 2nd depending on if you wanna play or you wanna allowed all people in tag have a chance to play.
1- just clean opponent field tributing, use sphere, golem, kaiju if you can.
2- just clean opponent field, s/t using duster, trunade, red reboot maybe.
3- synchro summon Final Sigma using nabla, division and other level 4 monster. (Make your Synchro attack twice with nabla, divide atk of the weakest opponent monster with division effect in gv)
4- boost Final Sigma with summoning Mathmech Addition, then reduce 1 opponent monster using Mathmech subtraction.
5- Equip Nayuta Billion equip spell to Final Sigma, attack to the weakest monster on opponent field, I mean lowest attack position monster on your opponent field and send with nayuta effect Mathmech multiplication and then activate effect in grave your synchro Final Sigma should have 9000 atk now, he can make double damge and attack twice so attack weakest monster in attack position and win.
6- I am guessing you will need some basic instructions to get the final result but should find your appropriate play style by yourself, now you have the general idea of what I try to do with the deck, you just need modifi a little and make your own plays to reach the final objective what is? Of course win by Otk in tag 3vs3 using Mathmech is hard so if you can do it I'll be proud of you pal.
Anyway I accepting funny ideas of anyone and questions too
