Malefic Dragon's Power

Your "Malefic Truth Dragon" gains ATK/DEF equal to half your Life Points. In addition, the following effect can be used once per Duel. Banish 1 "Malefic" monster from your Graveyard, and select 1 "Malefic Truth Dragon" you control. Until the end of your opponent's next turn, the next time that monster would be destroyed by a card effect, it is not destroyed.
