I support another Spiker that could work on offense teams. I would like it to be able to lead well, but that's probably asking for too much. Though, I don't mind a good Rapid Spinner. Another thing to add on to the Rapid Spinner idea, would to give it a type of Ghost / Steel. Ghost lets it spin block (block and spin yeah!), and Steel ensures it won't be too Pursuit weak. Give it Levitate and some decent defenses and we have a Salamence and Latias check (heck, could be considered a counter for the latter). Probably make it physically offensive so Rotom actually has a chance, if it was specially offensive, better off just giving it Scrappy lol. Unfortunately, we only have Shadow Claw and Shadow Punch as physical STAB moves, and those are pretty poor offensively due to the low base power (I guess a huge Attack stat could make up for it), resulting in a more stall-like Pokémon.
In short, I vote for an offense team Spiker unless a better idea shows up, but a Rapid Spinner would be good as well.
