I can see that doing really well with Toxic Spikes support, as that's your only way of beating Jellicent. Amoonguss would likely still be annoying but you could easily stall it out of Giga Drain PP with enough Calm Minds under your belt just by doing Rest cycles, though that of course leaves you more vulnerable to well-timed switches to things like Serperior.
I'm really considering trying that right now, but Specs Keldeo is just so good on offensive rain that I'm having a hard time convicing myself to do it. Maybe I'll make a team with Tentacruel support or something later.
