excavate cards from the top of your Deck, up to the number of cards your opponent controls, and if you do, add 1 of them to your hand, also, after that, place any remaining cards and 1 card from your hand on the bottom of the Deck in any order
It's also a Level 1 DARK Spellcaster, which is useful for many Extra Deck summons before it's destroyed by Instant Fusion
Because Pendulum Monsters on the field go to your Extra Deck if they would be sent to the Graveyard and can be Pendulum Summoned back later, in the long run, each Synchro Summon you make only costs you the Tuner you use for it, since there are no natural Pendulum Tuner Monsters
Its also a Level 5 Synchro Monster, so if you can revive your Accel Synchron or just Summon a second one, youll be able to get Stardust Warrior back on the field in no time at all
The monsters levels must also be equal to the rank of the Xyz monster
