Ooh. New post.
Spellforms... Interesting. Standard activation fixes a lot of potential breakages. I like that.
Going through them... The list is mostly fine.
You mistakenly wrote "Cold" for fire snow, which I assume should be chill.
How does Apparent Strength interact with someone trying to lift an actual person?
Shadowy Bodyguard might need a clause saying you need to be aware of the potential attacker. Not certain if it's necessary, but my spidey sense is tingling.
Illusory Monster should either be CR-based, or have a no-template clause.
What's a thunderbeast?
Reciprocate Spells seems... weird.
Although difficult... I'm worried about Persistent Hypothetical Future. It does require me to find a way for a sorcerer to have 14 6th level spells available in a day, so it should be ok.
Dead Eyes is probably a bit powerful, as a second level save or lose with a lesser lose on a successful save.
Change Form... Umm... Really? You took one of the most powerful spells in the game and included it in your system? 
Could I talk you into having a list of monsters you can turn into instead? Maybe a bonus to attack based on CL or something like that to make up for the lack of scaling? That way, you can use the newer polymorph rules.
Phase Transition... So, at level 12, I can take 12 10 ft cubes of air and transform them into a prison for whatever creatures where inside it, and those creatures start suffocating? With no save? I'm clearly not reading this right.
So... Change Form and Phase Transition are... problematic at best. There's some potential abuse I can see on some other spells, but it seems difficult at best. (Illusory Monster could actually be fine as an AoE will-save-or-die, since you have to be level 18 to even cast it). The way metamagic works at the moment means that you can start casting metamagic'd versions of spells as soon as you get them, which might be problematic.
Yes! Feedback! Okay, in order:
"Cold" will be changed to "Chill." Thanks.
It would make the person able to lift him, since that is a use of strength that influences another creature. I suppose it might be a bit subjective. Any ideas to make it clearer?
Thunderbeasts are remnant-based monsters. I'll post the list of them soon, at which point I'll put a link to it there.
Hmm... maybe the bodyguard is aware of it even if you're not? Nah, I'll change it.
I'll definitely add the no-template clause. I'm less sure about the CR change, but it does make more sense.
Yeah, it's a little weird. It doesn't work on most spells, but it's worth it for Baleful Polymorph, Irresistible Dance, etc.
If you can make Persistent Hypothetical Future given how hard I made metamagic on spellforms, that's fine by me. It's an entertaining, though not entirely invincible, build.
Is it really that bad, given that the duration is 1 round in every case?
I put in Change Form because the whole point of spellforms is to give remnant casters access to more powerful spells, spells they can't make just by combining remnants and spells that people would miss in their casters. I think I'll keep it in as it is, and the GMs with a problem with it (most of them, from what I hear) can nerf it as they see fit.
On Phase Transition: yes, it can drain all the air out of a room, but really that's not much of a concern for most creatures as they'll last several minutes. I'll add a clause to say that the created solid cannot occupy or surround the space of a creature so that the prison issue doesn't happen. Phase Transition is just supposed to use a common theme to simulate the effects of lots of different lower-level spells (Fabricate, Transmute Rock to Mud, Cloudkill, etc.). It may be a bit too powerful as it is, so my quick-fix solution might just be to shift it up to level 7.
I'm glad the system as a whole doesn't have too many problems. I like it, but I don't want it to be too weak or so powerful that it overshadows remnant magic. Also, is the way you calculate the number of uses per day a bit too complicated? It's phrased oddly, but I don't have a much better way to do it or a simpler way to state it.
