Articuno

With its sheer bulk and excellent support movepool, Articuno definitely lives up to its reputation as one of the legendary birds. Unfortunately, its Ice / Flying typing gives it a 4x weakness to Rock-type moves, including the ubiquitous Stealth Rock, which removes 50% of Articuno's health upon entry. Despite this disadvantage, Articuno's enormous base 125 Special Defense and respectable base 90 HP give it more than enough reason to be considered when making a team. It also makes an incredible team player since it has access to Heal Bell, allowing it to remove status ailments from fellow teammates. Articuno reaches a modest Speed of 295, enough to outspeed a respectable amount of Pokemon, and to Pressure stall opposing teams with Toxic and Substitute.
