Froslass

Although Froslass is not as fast as Deoxys or as sturdy as Forretress, she is still one of the best choices for a Spikes lead in Ubers. Unlike Deoxys, Froslass blocks Rapid Spin by virtue of its Ghost typing, meaning that its Spikes will not be removed so easily. Froslass can also use Destiny Bond to KO the opponent's Pokemon after setting up Spikes, making her more of a threat than Deoxys. Forretress is also often a bad choice for offensive teams due to its low Speed and vulnerability to being set up on. Froslass's spinblocking combined with her great Speed stat and ability to take down Deoxys and Rayquaza leads with ease make her an excellent choice as a Spikes lead for offensive teams that would normally struggle against those leads. Froslass's only downfalls are that she is frail and her attacks are weak, but the ice queen is meant to support rather than sweep.
