War Rock/Droll & Lock Bird
From YGOCounter
Usable
Target:
After the first add to hand.
Explanation:
Since most likely 
War Rock Mountain is used first to add a beater, using Droll here prevents them to add something during the Battle Step. They won't be able to search for cards like 
War Rock Medium for their setup to survive next turn since they can't OTK.
