The Resttalk set isn't given much credit, and has no explanation of the EV spread, which isn't optimal for a Defensive Gyarados of this generation.
[SET]
name: RestTalk
move 1: Waterfall
move 2: Stone Edge / Dragon Dance / Avalanche
move 3: Rest
move 4: Sleep Talk
item: Leftovers
nature: Impish
evs: 252 HP / 236 Def / 20 SpD
[SET COMMENTS]
<p> Gyarados is a very capable sleep talker and defensive pokemon in general. This set is designed to come in on physical threats and tank. Waterfall is for primary STAB, which works off Gyarados's fantastic attack stat. Stone Edge gives a wide range of coverage alongside Waterfall, Dragon Dance can increase the chances of a lategame sweep, and Avalanche offers a more immediate solution to Dragons.</p>
<p> Thanks to Intimidate, this Gyarados takes physical hits on switch-ins just as well as a Milotic with Marvel Scale activated. The EVs ensure that Infernape will never KO with Grass Knot after a Nasty Plot. Additionally, a +1 Life Orb Stone Edge from an opposing Gyarados will never KO even after Stealth Rock damage.</p>
--------
Before you gripe about Leftovers recovery being stupid, this spread takes special hits 2% better than a 252 HP varient, and isn't divisable by 2 for Stealth Rock.
