The exterior of the school after the invasion.

The Spade Branch is one of two known branches of Heartland Duel School in the Xyz Dimension in the Yu-Gi-Oh! ARC-V anime. They are rivals with the school's Clover Branch.[1]

The school trains professional Duelists.[2][1]

Prior to the invasion of Heartland City, Yuto, Shay and Lulu Obsidian attended this Branch of the Duel School.[3][4]

After the invasion, students from this school formed parts of The Resistance, among them Yuto, Shay and Lulu.[3]

Yuya Sakaki, guided by Yuto, journeyed to the school sometime later. The building had been abandoned and was all but destroyed.[4]
