Look guys, all that "Phalanx block all spells including soul spells" is just your speculation.
There is no mention either it can block it or it can not. It just remains unknown. Leave it at that.

May be it block all systematic spells but not all spell, there are exceptions. Phalanx is not invincible. This is proven by "Meteor line" already.
Just because it is not spelled out as an exception, it doesn't mean it absolutely can not be an exception.

If Phalanx is that good, Jummonji would be the top among 10 master clan, not Yotsuba or Saegusa.
Especially Yotsuba. They don't have quatity, compared to other clans. If they don't have better quality (aka. cool trademark spell) compared to other clans, there is no way they are on the top.
