First and foremost: if there are ANY questions feel free to ask, as I may forget needed details
Scale Masters are HARD to summon, you're gonna need 4 tributes for 1
Here's what you're gonna need, 2 pendulum cards in your pendulum zone, 1 equilibrium card in the e-zone, and one monster from your hand or field whose level equals that of your scale master. Your pendulum cards AND your e-card must have been on the field for 1 turn before you can use them as tribute for your scale master. The material labeled on the card will be in the follow two formats
1 Specific Pendulum + 1 Specific Pendulum + 1 Specific Equilibrium
2 "Archtype" Pendulum monster + 1 Specific Equilibrium
Scale Masters have very over powered effects but must always have the same draw back, that is that if the scale master is destroyed the controller of that card loses the duel.
Scale masters are kept in the extra deck
Hope this helps guys
