You are now a master at all games, and your Yu-Gi-Oh deck is upgraded to include a card of legendary Strength, such as a God card, a Number card, or any card that radically gives you an advantage.
You now magically summon monsters made of flesh and blood to be at your beck and call, summoning requirements apply and you need to be in a fight to tribute monsters, you may also actually cast spell cards and set and use traps while in battle.
