勝利の方程式
Winning Formula is a Yu-Gi-Oh! card. Compare listings from Singapore Yu-Gi-Oh! sellers on CardJio, then jio them on WhatsApp.
If only your opponent controls a monster: Declare "The Winning Formula is complete!"; Special Summon 1 "Number" Xyz Monster from your Extra Deck, except a "Number C" monster, then attach this card to it as material.
