5-turn (10 vs FGs) wins if this is a pet would make it so much awesome...
but the chances of getting this as a pet (probably appear as ??) is too little, plus you still have to look at the 50% chance (i think) that the oracle will allow you to have it as a pet, so yeah, minimal to the point of almost negligible (feels like waiting for a nymph already, eh? xD)
or just make it a spell which makes this creature (or probably a permanent, something with "sacrifice card: spawn(?) an asteroid on your field") to make it a non-stand-alone card??
or leave it as it is? it's awesome that way already
