this is obviously an exaggerated clip with infinite silk, and this is already a known strat but not publicly made aware as far as i know. u can consistently spear Phantoms pillar/steam attack to deal an extra 27 damage on phase change by sprinting away from the steam -> jump -> turn around -> spear
additionally (found by and made popular by Nebula), you can have 8 silk on phase change, get 2 spears off on 2 steam attacks, then 3 more hits + your silk heart and still get enough silk to spear after phase change is over.
i personally only use a spear on steam attack if i know i can spear after phase change again.
(forgot to mention that u can know the spear hits by seeing silk fly off the steam)
fyi this steam 0 cycle is super easy, you legit just need to do 2 dive dashes like i do in this video and then run through, the steam for some reason is fake and just doesnt do damage (similar to how you can run through organ cycles without taking damage after a certain point)
this seems kind of obvious but no top key runners seem to do it currently, you can do 5 pogo dashes before pogo dashing through the first two grand reeds with a 6th one and then 5 pogos into a 6th one after the downwards transition for the 3rd grand reed as well
the only tight part here is the 2nd grand reed, in my experience just ignoring its existence and pogo dashing as if that grand reed didn't exist seems to work quite well, you can also just not do it for that one or only do it if you feel you're fast in the room and it will still save time to do an extra pogo dash on the 1st and 3rd grand reed
saves like 0.45 over only doing 4 pogo dashes before each grand reed
