Theoretical All Cards Route Idea
It is possible to access chapter 3 through the sewers and it is also possible to access chap 2 from the sewers.
This is the proposed route which is open to some slight alterations.
1, Parakarry, BHS, Sushie, Chap 3 (sewers), Chap 2 (sewers), 5, 4, 6, 7, 8
It is also possible to do 5 before 2.
However there are a few problems with this we need a hammer upgrade to access chap 2 from sewers. If we had ultra hammer before chap 2, this would also cause a problem later as we would overwrite it with a super hammer and we need that to get ultra boots.
The only way to do the proposed route as of now is to trigger chap 2 with the desert rather than the super hammer which is really slow.
We Need any of these things to make this route faster than the current route (most likely)
1)Another Chap 2 trigger within the ruins (Pretty much impossible)
2)clip through the super hammer block
3)Ability to get ultra boots w/out ultra hammer, or w/ out lakilester
4)Retrigger chap 6 (not sure is this could be faster)
