The card you need for this are

1-3 just desserts

1-3 Ultimate offering

1-3 mysterious puppeteer

and at least 4 lvl 4 or lower monsters

 

This may be a little difficult but if it works u can leave your oppenent with 500 life points at the end of your turn. First play a just desserts (and as manu more as u can over the next few turns) and puppeteer facedown then put 4 monster cards (with/with out ultimate offering)(the more puppeteer's the better) as soon as possible. Then flip all your monsters (flipping your puppeteer('s) last) and u will get 2500-7500 life points then flip your just dessert('s) dealing your oppenent 2500-7500 life points dmg. If u do this right u will have an outstanding lead and will probaly win from this or a couple turns after.
