The Bridgehead problem. Most of the invasion theories seem to assume that the portal is infinitely expandable to accommodate whatever you want to shove through it. What if the doorway size id actually the physical limit? We have seen two people go through one at once and no more than that. That's an awfully long time to transfer the troops. Which brings us to the second problem.
I haven't noticed anyone assuming it's expandable - but let's say it's not. Yes the physical ability to move bodies through fast enough would be constraining, perhaps enough to warrant narrative comment and involve some other trick, but it's not that constrained
. You could slide a couple stacks of knights in there quick enough (maybe 6 at a time head-first by my estimate). Two quick fixes come to mind - distract the casters either by mixing their bodies with a lot of dirt ("why did he just send a huge mound of dirt through the portal? To stop us from using it?", or use Foolamancy (decrypt Jack first and veil the invasion). There's also a possibility Jannis' hippiemancy lasts long enough for it not to matter. (Or some other random trick that can prevent everyone from casting for like 30 seconds until Wanda can start decrypting).

The Great Minds and the Carnies are two factions within TMK, the regular Portal Park guards are still on duty, plus all the other casters who are currently neutral. A non-caster force would rapidly find itself in huge trouble as the full might was brought to bear on it before it could snowball enough decrypted. Tri-links would rapidly be improvised in every corner of TMK from whoever was readily available with unpredictable and unimaginable consequences, except they would be very nasty to be on the receiving end of.
It's the same problem as the sucker-trap. The GK force may be too small and too low on juice to pull it off since they don't know what they're up against.
GK doesn't have to win here though, they just have to have enough force to pose enough of a threat that a battle would be highly damaging for the MK - enough that they'd want to avoid it if possible. Parson can then give them an out "we just want to talk" or "we just want to get through to Charlie's portal" - which they might be agitated about, but agree to. He doesn't even have to pose a threat to the entire MK - just enough to convince any individual caster in portal park right now that it's in their best interest to hear him out first or leave him be (unless they want to join his army).
Moreover, the MK is likely not prepared for such a move. No non-caster has been able to move through the portals before, and so any invasion would have to come from the air or sea. With one noted exception: this was possible before from any side with a dirtamancer and croakamancer (move bodies, uncroak bodies) but it was likely unthinkable since attacking so many casters is basically a suicide mission (it still is for Parson, but it's at least mutually-suicidal), especially since uncroaked are weak, moreso when mass-uncroaked (decryption bypasses this limitation). Decryption is much more powerful and can be used repeatedly as enemy troops fall. And even if decrypted casters don't retain their abilities, nobody knows that - meaning Parson can threaten they do.
Overall, I don't think it's an unfair assumption that the MK is not prepared for such an attack, and any guards with standing orders to attack invaders would be prepared for individual casters at most (although I recon the MK might have a large air/sea defense). There are still plenty of casters in portal park to pose a threat, of course, but they are unorganized and probably aren't going to immediately attack before hearing out Parson (at least not with the confusion of the Thinkamancers, Predictamancers, and a Grand Abbie on his side).
(As for tri-links: Thinkamancers are required for the unravelling - if not the creation - of these links so I doubt any caster would be eager to use such a trick when Isaac and co are on Parson's side. Moreover, we've been told tri-links have been fairly understudied in erfworld (don't ask me to find the source though...) so I doubt it's the first thing casters jump to. It's possible the MK has an emergency Close-all-portals tri-link backup plan - or something else devastating to the portal plan, but Parson might be able to get enough force through immediately for it not to matter anyway.)
