I haven't used my blob in since I got to bio, so I'm forgotten that fact it seems.
you should, i normally sacrifice mine to lure/tank a few seconds to give me chance to AD once or twice 
Competition-wise, I've found myself only able to really successfully find Phreeroni when I'm in the mood to go MvPing (level 75 biochemist). Killing him was quite easy, so I never considered a lure. Well, Maya is *usually* there; she always tele'd quite annoyingly.
I was quite glee-ful when I actually was able to find Garm one day in Lutie Field. I got MvP, but the effect was rather spoiled when a Sin X dealt the finishing blow.
I went after Eddga; killing him wasn't worth the experience it felt like for all the trouble. Though my blob probably would have been useful for keeping the regular aggressive monsters off him (never considered it at the time---I just ice falchioned things before swapping back to bazerald).
I've never really thought of a MvP that I'd really have the bait for.
I pretty much was taught the throw an AD or two, fly wing, find again, repeat.
