Osiriswyrm strategies???

So I got an osiriswyrm and I’m wondering if anybody has any good strategies to use with it, so far I’ve been using it in conjunction with barricadus and puffoxin which is good but I feel like it can get better

Do you have: shadowstalker, minespider, mossgolem, or any other egg exclusives or mission monsters?

Not to hijack the thread, but what would be considered poison? Any move that deals damage over a duration like plague?

Plague is poison, yes.

shadowstalker
musharoo
puffoxin
osiriswyrm

seems to work well. just scapegoat musharoo, use plague with puffoxin. when musharoo dies, curse leaves them with poison. you can then use plauge to keep it longer, and even if puffoxin dies, it kills one of the opponents monsters. osiriswyrm just uses poison eat a bunch of times.
