Your Favorite Way To Compete With Fellow Clashers?

So I just started a competition series with EpicClashOfClansRaids from Lunar Rising (Daddy's Clan).

He chose the first round (loot challenge) and now its my turn.

I have some pretty excellent ideas, like all goblins/cc wallbreakers for highest percentage destruction, or see how many attack three stars you can get in a row, or maybe even design each others army for Pekkas Playhouse.

Does anyone have a fun challenge they have played with their friends, or maybe a troll attack you find hilarious?

I really want to annoy him with whatever I decide on...

Thanks for the ideas in advance!
