Card Text
Take 1 Level 1 Tuner from your Deck or GY, and either add it to your hand or Special Summon it. If you control "Junk Warrior" or a monster that mentions it, and this card is in your GY: You can Set this card, but banish it when it leaves the field. You can only use 1 "One-Way Synchro" effect per turn, and only once that turn.
