I feel very out of the Yu-Gi-Oh loop considering the most recently made card I have in my deck is Red-Eyes Darkness Metal Dragon, which, from the general consensus when I ask people about it, is a rather lethal card in Dragon-themed decks. 

Shit I hardly even know how Synchro monsters work let alone all this Xyz stuff. 

I should probably just stay in my closest with huge boxes containing hundreds if not thousands of old trading cards from the 1990s.
