By telling you all the flaws in your character all that does it let you improve it. But I will give you this one for free.
After you lose initiative your own bottle stops you from casting Subtle Counterspell. Nothing in the description says you can see through the smoke.
If we pretend you don't have the bottle, how do you counter subtle Time Stop?
With 2 to 5 turns to cast other spells, you will end up being defeated before you even get to go. There are too many combinations of spells after this Time Stop to explain how you would end up defeated. Improved Invisibility removes subtle counterspell from the equation. Now you are a guy standing there for 1 to 4 more turns while other spells are cast.
Still, nothing here can really harm the sorcerer.
