Activate this card by sending 1 face-up "Infinite Machine" in your Spell & Trap Zone to the GY. This face-up cannot be destroyed by an opponent's card effect. Neither player can target "Timelord" monsters you control with card effects, or return "Timelord" monsters from the field to the Deck. Once per turn, if you control no monsters: You can Special Summon up to 1 "Timelord" monsters each from your hand, Deck, and GY, with different names, ignoring their Summoning conditions.
