I'll pass over the message for you, he's coming to play at my house on Friday.
I believe that the Yoshi-Nightmare matchup is very hard though. Yoshi is extremely fast and damaging, has strong pokes, is pretty safe (if you play him safe), and can interrupt extremely well.
I heard that the NM-yoshi matchup is in NM's favor though. However im not sure about this. It was just that he was being hit by the same stuff very often throughout that video series so thats why i assumed that he wasnt familiar with the matchup.
