[Super Mario Bro]

I actually think HP Fire should be slashed over Draco Meteor on the Screens set. 0 SAtk Draco Meteor doesn't even scratch any of the things that switch into him, while HP Fire scores an OHKO on CB Scizor and does a good amount of damage to Ferrothorn.

And Dragon Pulse definitely deserves a slash on the Specs set instead of Thunder. It's a much more conservative STAB than Draco, and is very useful in situations where you want to spam a consistently powerful move without needing to switch out. In my experiences, it's even better than Psyshock as a secondary STAB.
