Monster to share

I was just looking at my friend list and was wanting others opinions on which mon I should share. Currently I’m sharing shadow hunter, which can be a beneficial, but if the other team utilizes poison all before two kills you might as well put him out to pasture. I also have bovolcis but unless you plan appropriately, he could end up hurting your team more than helping. I have penguinator fully evolved again if used right can be great, but has too long of a wait before his first move and can be killed easily if the other team is ready for him. Oh yeah, I also nebolronix and asrtodragon, may the rot on my bench for thinking of themselves as legendary, or hell for that matter. Bastards.
Another thought on the subject though is do I want to change. Have some last biter friends along with other quality mons and I don’t want to lose them if they actually like to use SH because he fits their team. Thoughts?
