Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 "Ninja" monsters During your Main Phase: You can Set 1 "Ninjitsu Art" Spell/Trap directly from your Deck. You can only use this effect of "Ninja Grandmaster Saizo" once per turn. While this card points to a monster(s), this card cannot be targeted for an attack, also your opponent cannot target it with card effects.
