Magic The Gathering: Arena || Dragonspark Reactor Closer w/ Rakdos Sacrifice

Opponent threw a Good Game on the table before initiating combat, he was far from lethal so I figured he realized I would untap with the Dragonspark Reactor primed and ready, and Opp was gracious enough to let me get my payoff so I figured I would record. Big thank you to my opponent here for that!
Started running Blood Hypnotist and Blood Servitor, the latter is a 2/2 artifact creature that ETBs with a blood token and the former is a 3/3 that can’t block but makes target creature unable to block the first time you sac a blood token in your turn. Which works great with Anvil, or even just when you draw-discard, especially in the early game!
