Hello I am the resident baba expert so I'll try to respond to some things
Turn invisible so baba cant even see him
I guess it's not on Baba's profile (maybe ill make a sneaky edit?) but baba can do NOT BABA IS NOT HIDE (prevents anything other than baba from being invisible). And baba, to play it safe, could make rules with NOT BABA that refer to everything except baba regardless of whether or not they're invisible.
If baba possesses something, does baba dodge the EE? Who knows... Baba can also do something quite nasty, which is the rule EMPTY IS BABA. All empty space turns into Baba. So, if you EE baba and there's just empty space where baba had been, said empty space will transform into a baba. (On baba's page, see Void Manipulation. In the parentheses it says baba can control the properties of nothingness)
Has danmaku to overwhelm baba
NOT BABA IS STILL (on baba's profile, the effects of STILL are under Spatial Manip)
Self resurrect
Damage null
2 layer possess with cappy
NOT BABA IS EMPTY transforms everything that isn't baba into empty space
To me it seems like the gold flower empties the blocks it touches. Text blocks in baba don't have anything so I don't think anything would happen (same as if you hit an empty block with gold flower)
That's another thing that bothered me. What makes the word block things "Law Manipulation" when the way you wrote it makes it sound more like run-of-the-mill
Text Manipulation?
From the wiki, it seems that Text Manipulation is about manipulating the literal text of the story (for example, a character editing a paragraph in the story they're in to make it describe something else). The text in baba is you is not the narrative of the game, nor does it exist in a noncorporeal sense like story-text.
Sounds like something that you should get a second opinion on. Pretty sure Law Manipulation involved screwing with the very workings of the world, which I don't think simple "monkey see, monkey do" qualifies for.
The text blocks in baba is you are the very workings of the world. They are what define what properties things have. If there are no text blocks present, nothing in baba is you has any properties (there are some exceptions but dont worry about that)
