Basking Broodscale is a card with high combo potential and have already seen some discussions surrounding pairing Broodscale with Sadistic Glee & Thoughtpicker Witch
You can play a single copy of Mental Misstep in Vintage, or in Highlander formats (including Commander!), but otherwise, youll have to read about this menace in the history books
