Glimmering Angel: 3W 2/2 flyer B:Cant be target of spells or abilities until end of turn
 
Coalation Flag: makes opponent choose enchanted creature as a target if legal
 
 
i think you got the idea
 
they play spell target angel and for 1 blue mana counter any spell that may target a creature   
 
 
 
i not 100% this works but im almost positive
