Stadium possession / Falkner trainer card

[GroceryTurtle]

Falkner trainer card states: "Draw 2 cards. If you have a stadium in play, draw 2 more cards." if its not MY stadium that I played, does it still count for me to draw 2 additional cards?

No. The game knows who owns the Stadium.
That's why the proper placement of a Stadium is facing it's owner, not sideways, as has become popular.
