Help me /vp/

I don't know what to do with my Roserade. I was thinking of a support Toxic Spikes set, but I'm mainly a Battle Spot/Maison 3v3 player, so I don't know if a Toxic Spikes set is worth the slot, or if an offensive or SubSeed set is better.

For the record, it's Hasty nature and it has Natural Cure.
