Wee Dragonauts has been one of my favorite cards since I started playing with a pile of my friend's random Ravnica block cards.

Alternatively, use a Bant defensive enchantments package like Privileged Position, Sphere of Safety,Ghostly Prison, Greater Auramancy, Propaganda, and things of that nature.
