Okay ArchPhantom posted a core earlier that somewhat inspired this one:
+
This core absolutely dismantles stall and does well against balance. What threats Char-Y doesnt destroy (Namely Chansey, Lati@s, or creselia), Heatran can trap and take out. While both pokemon may at first appear to have overlapping weaknesses, they actually have fairly good synergy as they only share a water weakness. Also another fun thing is that Heatran can often benefit from Char-Y with sunboosted magmastorms.
Useful teammates that I have found are Voltturners such as Lando-T, Raikou, or scizor. Also this core does not enjoy hazards, especially Char-Y, so a spinner or defogger is mandatory. Some pokemon that I have noticed can give this core trouble are Azumarill, Lando T, and Keldeo so make sure to keep checks for these mons specifically. (I know there are probably a few others that I cannot think of atm).
So yeah if you guys have any comments or nitpicks I'd be glad to hear them n_n
