The creature-returning isn't contingent on the exile. I expect shenanigans with Nim Deathmantle. Sacrifice it to something, put the Deathmantle's trigger on the stack above the Monstrosity's. Pay 
, get it back, get two other creatures. And you still get the effect from whatever your sac'ed it to (Greater Good, anyone?)
Edit: @Bazzoka - Yeah, you're missing the fact that if the card changes zones, the ability loses track of it. Just like Vedalken Mastermind/Mangara of Corondor can work together to exile a creature every turn, by bouncing it in response to the exile.

Compare to Terra Stomper.
That extra 
is big deal, and is probably the difference of a turn to get him out. What kind of decks are you expecting to fight?
If they are fast, you want the stomper.
If they are counter heavy, the stomper again.
This card fits quite nicely everywhere else though. I love cards that thumb their nose at Wrath effects.

The "at random" clause makes this card a lot less desirable. I'll probably run two in my casual mono-green stompy anyway.

@WhiteWizard42 I don't think it would work like that. Sure you'll get it back but then the exile effect will still trigger, rendering the you paid to go to waste. As much as I would like to be able to do this for heavy reanimating, it just doesn't work. Unless, of course, I'm missing something.
EDIT- WHOOP, sorry, I didn't think it would apply to this kind of situation. For some reason it didn't click.

This is not undercosted when compared to good creatures. And will never see constructed play just like Terra Stomper never did. Green fatties have to be much more agressively costed to match the best like Phyrexian Obliterator, Consecrated Sphinx, Baneslayer Angel, Wurmcoil Engine or even Bloodgift Demon.

I misread this as returning them to your hand. Now it's even better!

ANOTHER rare bug that's useful. I'm tickled pink. Return my Hornet Queen's back to play? Sounds good.

Sooooo good! Puts the Pelakka Wurm to shame. If you get Wurmcoil Engine for six in any color, this is what you're supposed to get for seven in green.
