It has two abilities: you can Summon a Dracoslayer monster from your Deck (but you cant use it for a Synchro Summon while that monster is face-up on the field), and you can destroy any Pendulum Monster on the field or any card in a Pendulum Zone (if you do, you shuffle a card on the field back into the Deck)

Sorin of House Markov / Sorin, Ravenous Neonate Sorin of House Markov is a very flexible 2-drop
