Hi-Speedroid Reboot

Can be used during a turn on which you have not Special Summoned any monsters. Send 1 "Speedroid" monster you control to your Graveyard, and then play 1 "Speedroid" Synchro Monster with the same original Level as the monster you sent to the Graveyard from your Graveyard in Attack Position. This Skill can only be used once per Duel.
