Forum:Lady in Wight/Order to Charge

The text on Order to Charge says when the card resolves, tribute a selected normal monster and destroy 1 monster you opponent controls. The Lady in Wight protects level 3 and lower zombies from the effects of spells and traps. If I have a face up Lady in Wight and a face up Skull Servant(Level 1 normal zombie) when I activate Order to Charge, I know I wouldn't tribute Skull Servant because it's the card's effect, not cost, but would I still destroy one of my opponent's monsters?
