Effect: By removing this card in your graveyard, during your main phase, select one monster you control. Until your opponent's end phase, that card cannot be destroyed by battle and all battle damage you take involving that monster becomes 0.
The new Necro Gardna? The downside of this card is it must be removed during the main phase and it has to be done during your turn. Konami learnt their lesson.
However Necro Defender ensures you stay in the game and the monster you select will be able to make it through to the next turn to use its effect to gain more advantage.
Possibly maining one in Lightlord?
Quite balanced card overall. i'd give it a 6/10
