Mind games exsist everywhere, the thing about mind games are that they are freeform and based on your oppenant. Some good ones with reptile might be not using sfb oki on knockdown at all in round 1, then start doing it in round 2. Basically you want to train your opposition to expect one thing then throw them a curveball this is how you mind game. Other reptile mind games might be using a lot of low slides in your mix ups then when they get used to this start using the overhead, and even the ex overhead acid hand, rather than just mixing it up this will train your oppenant again into thinking one way just to get reamed by your overhead.
Be unpridictable but effective, and always, always think ahead and watch your opposition.
