The guy has basically one modern showing during Day of Vengence, he was Spectre's first target when no one knew Spectre was on a rampage and Spectre was unable to kill him though he won without any long lasting damage to the Spirit of Vengence.

Shazam with loads of prep died to Spectre, Fate with prep's only hope was a pyric victory strategy, Blackbriar Thorn was the only surviving memeber of a cabal of about 50 sorcerers and even he was reduced to a seed and hasn't been seen since. These guys are major magical heavy weights of DC and had far more prep and help than Phantom Stranger had against Spectre

While his power is ambiguous at the very least he is a peer to Loki at apex he could be considered more a peer to Odin though far less direct like a Watcher would be

> IF the various Magical beings were trying to "stop" a Phantom Stranger going "mojo" crazy as Spectre did, trying to destroy ALL Marvel Magic...
