DRAGONAIR - WHAT IS THIS? Believe it or not, Dragonair is a pretty good Dragon. It works best as a stalling supporter, but is actually pretty good. With Shed Skin, it is one of few Pokemon who can utilize Rest fairly well. Pair this with Toxic, Rest, Sleep Talk, and Dragon Rush for a surprisingly effective Sleep Talk set!
SALAMENCE - This thing is a BEAST. It has Outrage, Dragon Dance, Aerial Ace, Crunch, Flamethrower, EVERYTHING. It's got the stats to be a mixed sweeper too, which is phenomenal.
FLYGON - A Ground / Dragon Type with Levitate. need I say more? Claw Sharpen, Dragon Claw, Earthquake, and Fire Blast or Stone Edge, will make an incredibly useful sweeper set. Its generally incredible performance as a Scout is also better now, because of Dragon Tail. It can now scout and sweep at the same time!
ONONOKUSU - 147 Base ATTACK? Oh. My. GOD.
DRAGON DANCE. OUTRAGE. IRON TAIL. EARTHQUAKE. PURE DRAGON TYPING. USE IT WISELY.
KINGDRA - How do you NOT use him? Only one weakness! Waterfall, Dragon Dance, Outrage, and Yawn is all you need to make flawless sweeps! Yawn is mainly used to force a switch toward a stronger foe.
SAZANDO - Like I've said, I think it makes a better scout or tank, but it can sweep as well! Packing Cheer Up, Outrage, Crunch, and Flamethrower, Sazando can really put dents in teams. Its natural bulk makes it plain versatile.
