1) "Yet, so long as Tatsuya still held onto the handicap of not utilizing attacks through the Idea"

• Attacks made directly through the Idea would be effective. In other words, Tatsuya's innate specialty. This clause appears to imply that something like Trident (the 3-part Decomposition magic) would be effective.
• He refuses to use such magics for obvious reasons.

2) "then he was a deficient Magician who could not use magic that directly influenced physical phenomena"

• Tatsuya's specialization leaves him incapable of traditional magic, i.e. physical phenomena alteration (with the exception of Flash Cast).

In other words, it's suggested that given Tomitsuka's anti-magic armor, only two types of attacks are effective against him: 1) attacks made through the Idea, something that's only possible for Tatsuya, but which he cannot use in this situation, and 2) magically altered physical phenomena which Tomitsuka does not have the ability to affect (because he's "Range Zero").

In short, there are two techniques that Tomitsuka is susceptible to, and the only one Tatsuya has access to, he has sealed. That's what makes him a bad matchup for Tatsuya, but not necessarily anyone else. A normal magician who could avoid being destroyed in close combat would take him down with ease, which is why I pointed out Mayumi's Dry Meteor, which she used to subdue Lu Gonghu.

attacks throught the idea don't work because even if the magics is aimed at the info of the person the pressure of the psion armors breaks the magic sequence, that's why mist dispersal a magic used throught the idea is ineffective.
