First I play the magic card Shied & Sword and change the defense points of your defense position Big Shield Guardna into his attack points.



[ATK100/DEF2600] » [ATK2600/DEF100]



Next I send Wynn the Wind Charmer and Wind Effigy to the graveyard to summon Familiar-Possessed Wynn.



[ATK1850/DEF1500] Monster Effect: During battle between this attacking card and a Defense Position monster whose DEF is lower than the ATK of this card, inflict the difference as Battle Damage to your opponent.



ATTACK WYNN, DESTROY HER LAST DEFENSE AND END THIS DUEL!
