<u><div class="middle"><strong><p>Explanation</p></strong></div></u>
<strong><p>This set is meant to take advantage over Weavile's high Attack stat. Ice shards letting you go first, plus bonus STAB damage. While Night Slash is a dark physical attack, it has a boosted critical hit rate, also gives off STAB.</p></strong>
<strong><p>Substitute+Leftovers giving you a chance to use substitute 5 times and rarely more also with the ability "Pressure", if you face an attack that can OHKO (One Hit Knock Out) you but has 5-10 PPs you can stall it out.Another advantage of substitute is if your opponent switches out, uses a weather effect {sunny day, rain dance etc.), uses a status effect move (toxic, attract etc.), uses ineffective attacks, or just misses you can set up Focus punch which eliminates one of weaviles weakness; steel type pokemon.</p></strong>
