I do have to weigh in that in the specific case of MP busting, I would tiebreak for the view that makes it less effective if it comes from a game in which MP is easily restored by storebought items anyway! MP restoration is rare as hell to be DL-legal, but it's NOT so in-game, and thus MP Buster is not a terribly dangerous move because you just toss an Elixir and go about your merry way. I feel the same way about Shadow Hearts MP attacks. They're already inflated in the DL, no need to tiebreak and have them hit resources they don't even explicitly get in-game!
Godlike
Yuna (Final Fantasy X) vs Loki (Valkyrie Profile): Yup.
Zophar (Lunar: Eternal Blue Complete) vs Adramelk (Laggy Fantasy Tactics): Barely manages the OHKO to me.
Heavy
Wren (Phantasy Star IV) vs Queen Zeal (Chrono Trigger): Replaying CT has increased my respect for her speed (don't hold Panel charms against her, enemies in CT are faster than stats indicate) but decreased my respect for her HP. Not sure where that leaves her here. If she doubles below half HP she wins (screw this MP Buster nonsense, Hallation + poke ftw). Still, Wren can just wait for a chance where he can blitz Zeal through a lack of doubles (i.e. lower her below half HP just after a double) and Zeal's below half HP phase just doesn't last that long, so yeah. I do let Zeal counter MT these days but it's not enough.
