It is a glitched skill that was used by Aster during the tag duel event. Basically, he uses the powers of his awesomeness and hotness to freeze the whole duel and force you to surrender to him to get back to the game. A true pro tactic.
Afair: It adds 1-3 Destiny Heroes from your graveyard to your hand + 1 poly from your deck. This mean dangerous is coming again...
Zane had a similiar skill where he added Cyber Dragon from the graveyard to the hand. Never glitched the game for me. (^.^)
I wonder if Electrodes will end up being something akin to D.D. Miasma for both players. In theory, that's a lot of burn damage, but Shadow Game hasn't seen a lot of use, so it might be fine. Alternatively, it might just burn a set amount each turn, or when a player takes damage some other way. (The last point would more closely mimic how the devices worked in the anime.)
