I once made a silly rogue Deck, where I had all three Regi's as attackers and I used Parasect from Breakthrough to accelerate energy to all of them at once in a single turn... It flopped against Night March at the time. =/
On the other hand, this Registeel's synergy to Regice for a card effect looks quite interesting, and depending of the moves of the other Regi cards, it might make for a fun deck to try out!
