Interesting deck. I would personally change Copper to SkrumxxT and Hawk to Eris.
Copper and Hawk don't really add anything to the deck (appart from stop opp: ability but mostly this is used for 1HKO's but drs stop this). also due to there only being 2 Sentinels you will not usally get them both at the same time and Copper on his own is not as good as SkrumxxT (SkrumxxT power is also more stable).
Battery.....hmmm obvs id use guru if possible but im not that lucky.
Ive seen a variation where Caelus Cr/Dwan were used overthe 2 sentinels...i tried that but found it too fragile and too DR orientated...a card like Fixit simply destroyed the deck
Personally i think Hawk is a necessity due to the SOA which is invaluable...he doesn't need his bonus and is much more viable than Eris
Copper is the only card id consider removing....but his 2HKO options are beautiful and again he doesn't really need his bonus to be good
Maybe i could switch Copper> Skrum and leave Hawk or splash Jackie Cr for lower star count SOA...what do you think?
