Overclock feeds a token or a specified Digimon to the machine at the end of your turn, and in exchange this Digimon attacks the player without suspending. That's an extra security check per turn that doesn't open you up to a counterattack. Decks built around it want a steady stream of cheap sacrifices, so the token generators are as important as the attacker itself.
16-34-1. <Overclock> is a keyword effect. At the end of your turn, by deleting 1 of your Tokens or 1 of your other specified Digimon, the Digimon with this effect attacks a player without suspending. This is shown on cards using text such as <Overclock ([Puppet] Trait)>. 16-34-2. <Overclock> is a trigger-type effect that triggers at the end of your turn. (For details, refer to 15-8-3 "Trigger-Type Effects") 16-34-3. "By deleting 1 of your Tokens or 1 of your other specified Digimon" in <Overclock> is an optional processing condition. If the content of that condition is executed, the processing for "the Digimon with this effect attacks a player without suspending" will be mandatory.
