easiest, safest way to capture monsters?

Thoughts?  Suggestions?

Well depends what kind. Most material monsters have protect and hold ground so protector killer works well.

Anyone with a polareon can sleep a monster and use nightmares grip to take it to 1 hp

Other than that, just trying to get its hp as low as possible without killing it is the best thing you can do

My general tactic is to use protector killer (non charged) or poison to lower it to red.
For ingredient monsters most have hold ground, so just blast them to 1 Hp.
