Effect
Target 1 Defense Position monster you control with 1000 or less DEF; draw 1 card, also that monster cannot be destroyed by battle this turn. You can only activate 1 "Draw Muscle" per turn.
【Regarding the ① effect】
Cannot be activated during the Damage Step.
You can target a monster that is already unaffected by battle destruction.
The effect is considered to have finished resolving once you perform the "draw 1 card from your Deck" action.
If the targeted monster has left your Monster Zone by the time the effect resolves, you still perform the draw.
If the targeted monster is in face-down Defense Position by the time the effect resolves, the effect is still applied as written. (You draw 1 card from your Deck, and the targeted monster will not be destroyed by battle this turn.)
If the monster to which this effect was applied is no longer face-up in the Monster Zone, the "cannot be destroyed by battle" effect stops being applied.
