Mountain (terrain)

The Mountain terrain.

The Mountain terrain was shown briefly in Duelist Kingdom. It was used by Mai Valentine for her "Harpie Lady" monsters. It appeared to power up Winged Beast monsters.

In the Yu-Gi-Oh! TCG, the terrain is represented as the Field Spell Card "Mountain".

In early video games, the field can be changed to Mountain by activating "Mountain", which grants the ATK and DEF changing effects of "Mountain" to the affected area.
