God-Mind: Begone Thought! (300) (Requires Physical Strength, Debuff Proficiency, Telepathy, Active God-Mind Transformation)
[spoiler]In his God-mind state Strazio’s tactical awareness is heightened to a point where he is able to identify which of the opponent’s abilities and moves are the greatest threat to him. Using a sudden surge of both physical and mental stimuli he is able to temporarily disable his opponent’s access to a single move. To begin this attack Strazio must spend three seconds charging, during which one of his hands is unable to do anything, but he is free to move, take hits, and attack otherwise. As he charges white energy begins to wreath his chosen hand and after three seconds his hand becomes a blazing white endoskeleton. Once fully charged he can hold onto the move for thirty seconds before it dissipates. To activate this attack Strazio must have witnessed the move he wishes to disable in person. He then reaches out and grabs his opponent's forehead. Once contact is made the stored energy blasts through the target’s brain scrambling their thoughts. Physically the attack leaves behind superficial burns, but mentally the target is unable to recall how to effectively use the chosen move. This effect lasts for thirty seconds. This can only be used once per fight and should the target’s TEC be higher than Strazio’s the move fails. Should :Begone Thought!” target a move that is a physical object, such as a sword or gun, the target merely loses the ability to use it effectively I.E. they forget their fighting style and can merely swing their sword  or fire their gun as if they were untrained. Moves such as claws, fangs, or other inherent parts of someone’s body cannot be disabled. Super Moves are also unaffected. After application Strazio is heavily winded for a few seconds.[/spoiler]

An example of what you mentioned, Jeff. 
Sealing moves is fine if you've got a charge time and fatigue cost - but only for limited durations. I'd expect SP to be required for anything longer than a minute or so.
