Skarmory

Skarmory is simultaneously the tier's premier Spikes user and a heavily utilized physical wall, using its access to Toxic and Roar among other moves to distinguish itself from other Spikers. Its Steel / Flying typing is also perfect for its role as a wall, leaving it without any physical weaknesses and with a resistance to all but two physically attacking types, namely Rock and Fighting. However, two exploitable weaknesses to specially attacking types make it vulnerable to Fire- and Electric-type attacks. Despite this, Skarmory is an incredible floor-raising Pokemon that should be considered on everything from Spikes stall to offensive Spikes teams.
