first off I would like to ask why you are using a Swampert in the OU metagame as a attacker. If you are to use it I recommend that you use it as a defensive wall with SR instead of the all out attacker that you currently have. Your genesect set looks strong (rock polish is a personal fave). You might want to use a stronger choice scarfer such as terrakion as it revenge kills much more efficiently. Heatran you might want to replace with another special wall that resists fire if you give swamper SR but if you choose to keep Swampert the same you should keep the Heatran set. Gliscor looks good but you have no water resistance in your team. Finally for magneton you should upgrade it to a magnezone with choice specs for a stronger HP fire.
