yu gi oh side deck The Art of the in Modern Yu-Gi-Oh! What is a side deck?

This deck picks one of two creatures (depending on which one works best) and is unable to play the other

From the The Secret Forces set

Clear Cube X DARK Level 1 [ Machine / Effect ] ATK 0 DEF 0 You are unaffected by the effects of "Clear World"

Its not an expensive deck, making it even more desirable

However, aside from the switch (or button) itself, this card heavily features a floating Pokeball as its focal point, explaining the card's value

This deck archetype is great for new and returning players since it keeps the mechanics relatively simple while still being able to pack a massive punch and players who chose the Power of the Dragon Starter Deck after clearing Yu-Gi-Oh
