Shooting Star Road Begin the Duel with 1 "Junk Converter" in your Graveyard. In addition, the following effect can be used once if you have "Stardust Dragon" on your side of the field. Play 1 "Formula Synchron" from outside of your Deck. If you play a monster with this Skill, only WIND Dragon-Type Synchro Monsters can be Special Summoned from your Extra Deck until the end of your opponent's turn. This Skill will only activate if you begin the Duel with a Deck that has 8 or more cards that are "Junk" monsters or "Synchron" Tuner monsters and an Extra Deck with 4 or more cards that are "Junk," "Synchron," or "Stardust" monsters.
