Phantom in Shinjuku chapter is referring to 'illusionary being' such as folklore ones.

Avenger is combination of King of Currumpaw (Heroic Spirits, real creature) and Sleepy Hollow (folklore creature). Assassin is combination of Yan Qing (Heroic Spirits) and Doppleganger (folklore creature), Archer is combination of Moriarty (Heroic Spirits, originally Caster), and Freischutz (folklore creature).

Phantom have no value worth of heroic spirits, they can't be summoned despite promising skills. Da Vinci and even Holmes believe its impossible to do so, let alone fusion with another Servant.

In Shinjuku, this is achievable after Baal exploring summoning method further using its capabilities as wish-granting machine for sake of revenge to Ritsuka/Gudako; similar to how Medea hijack Assassin container-- Baal find way to hijack the summoning system, allowing abnormal summon, fusing Heroic Spirits with Phantoms to augment their abilities.

The way Baal found requires Shinjuku thrown into state where Common Sense doesn't exist which is why we saw Shinjuku in such unnatural state.

This is also the reason why Sherlock capable to fusion with Dantes despite neither of them are Phantom, Shinjuku now is a place where Common Sense doesn't exist, so its possible to do similar fusion when one have the knowledge-- and we know both--Sherlock and Dantes are among smart Servant on TM-verse.
