Are suicide leads still popular?
Well, yes and no. As it is often harder to keep offensive momentum in CAP than it is in Standard, many players prefer to use bulky Stealth Rock Pokemon like Swampert or Metagross. On top of that, it is also easier to find good Rapid Spin users in CAP, as Fidgit, and to a lesser extent, Colossoil, do an excellent job. On the other hand, the CAP project has given us a very fun new Spikes lead to toy around with: Syclant. Syclant has all the requirements of an awesome offensive lead: high Speed, Spikes, Taunt, Compoundeyes to help its powerful STAB moves, and priority in Ice Shard. One could almost say the only move that Syclant lacks is Stealth Rock!
