Hi. In playing EH with the Dreamlands sideboard, if a Gate is spawned on a Dream Portal on the main board, it is placed on the corresponding site in Dreamlands, But there are also Dreamland-specific gates. So in our game, there were times when a specific Dreamland site had two gates--one from spawning the specific Dreamland gate disk and one from spawning the main world city gate that corresponded through a Dream portal to that Dreamland site.
Is this legal? Can you have two Gates on a single site? Or is one of the Gates just not placed (it doesn't spawn due to interdimensional interference!)?
