To be honest, I could see Taichiīs "special move" become his imagination of being someone else. Buff touched upon that topic. So Taichi can just flip a switch and imagine his opponent being Chihaya. Now let him indeed imagine to bee Suo ... what would happen? Sure, itīs unrealistic to actually match those "imagesī" capabilies. But it could get him close, maybe even match them, only with a higher error margin.
Itīs be a speciality befitting Taichi, whoīs all about his brains. Heīs like a computer that keeps gathering EVERYTHING. Thatīs why heīs the best at memorizing cards. Let him memorize Suo and ... start playing like him.
