Doublade

Doublade is a staple in the Almost Any Ability metagame, standing out as one of the best checks to nearly every physical attacker in the format with its high physical bulk. Its excellent typing gives it a wide range of resistances and immunities, including to Flying-, Fairy-, and Ice-type moves, making it resist all three common types of priority moves as well as allowing it to spinblock with its immunity to Normal-type moves. Doublade can choose between three excellent abilities in Flash Fire, Regenerator, and Levitate, all of which change the way opposing teams are forced to deal with Doublade. It can even function as a late-game sweeper with Swords Dance, making it far less passive than most other walls. Doublade is only held back by its lack of recovery, its severe weakness to Knock Off, its somewhat mediocre Special Defense, and how easily it's walled by the metagame's most common defensive Pokemon.
