yugioh pyro deck Duelists and Friendship The Best Pyro Monsters In

You can only use this effect of "Ursarctic Septentrion" once per turn

When this card is Synchro Summoned, send all cards your opponent controls with the same Attribute as this card to their owner's hand

That's an archetype where you cast instants and sorceries and trigger things like Guttersnipe and Young Pyromancer for stuff

While I did eventually start buying and collecting cards myself with the Fossil set a little later with pocket money, I am thankful to my friend for sharing this, and later many other cards, such as a Base set Mewtwo, and even a Shining Magikarp from Neo Revelation

There aren't too many variations that can be used in this deck, outside changing the number of cards used for a few of them
