...and its clone question

[RDOOD]

So is playing the Star Munchkin "...and its clone" card effectively the same as playing Wandering Monster plus a monster card?

So let's say that my combat strength is 10. I open the door and find an Awful Green Thing. My opponent plays "...and its clone". Am I now basically facing one monster who is at 16, which means I lose, or am I facing two monsters of 8 each, both of which I defeat?

I am assuming it's the former, but we weren't sure, because the Wandering Monster card explicitly says that you combine the strengths, but the "...and its clone" card doesn't say that.

Thanks -
