off the bat it looks solid a couple things though.. bisharp is missing 4 evs and I highly recommend putting 252 speed evs and an adamant nature, generally you want heatran special defense evs to deal with certain threats as well as complete your defensive core (you generally you dont need the spa).. I would highly recommend putting rocks over flash cannon on heatran (the need for flash cannon is very low) and putting spikes on ferrothorn instead of rocks so u can hazard stack, from experience assault vest melmetal helps deal with key theats much better then choice band does (I can give you a set if you want) Ferrothorn looks good (besides spikes) I always like to use body press so magnezone can't set up on you but that's up to preference but you definitely want seed bomb or power as its grass stab is very important, and specs aegislash generally far outperforms life orb and doesnt let it take chip life orb damage and you can still use sneak if you need it and simply run steel beam or toxic for the fourth move
