So yesterday I found out you can go plus three with a full board with karakuri's yesterday. With two cards.

Use speedtop, get red eye dice, synchro in lvl 7 karakuri use effec to summon lvl 4 tuner , use iron call for top, synchro again bring out lvl 2 tuner. xyz into galaxy stealth jet with the karakuri's. Use effect for level 6 tokens. Synchro and use the effect for two more of the big guys and then special summon a karakuri strategist. Draw three. Set Zero Gravity and hope they don't have raigeki.
