Hey I got a great combo that helps at the end of the game.  I used it plenty of times and won my way through.  Okay first play Jawbind then Wingardium Leviosa or Dungbomb and Unicorn works.  This helps you prevent anykind of damage on the next turn ..well except adventure damage.  Unicorn is helps too if you run a spell deck but if you run a spell + creature  then you don't really need unicorn you can just stall for your creature.  It does miricles for me and does a great deal of annoyance to most opponents.
