Megachomp can come in on anything besides HP Ice from Zapdos, then proceed to SD and OHKO both members of the core with Edgequake, as it's faster than both. Another mon that I really like against this core in particular is SubSeed Serp, who can obviously beat fini and pretty easily wear down zap into range of Leaf Storm and stuff of that sort, preferably with Grassium but Leftovers is obviously fine too.
