[SET COMMENTS]
<p>Though Meganium is normally viewed as a defensive Pokemon it can still make a formidable sweeper with access to Sword Dance, a 200 base power move, and Overgrow. Meganium should come in on something that it can force a switch on and begin the Substitute and Sword Dance cycle. Eventually, it should Substitute down to activate the Salac berry and Overgrow and from there can proceed to sweep with boosted Seed Bombs and Flail. Surprisingly, Grass and Normal gives remarkably good coverage in the UU environment; being resisted only by Drifblim, Shedinja, Mawile, and the seldom seen Wormadam.</p>
<p>At first glance, this set may seem to be an inferior Flail Leafeon given Leafeon's higher Speed and Attack. However, Meganium has one significant advantage over Leafeon and that is its Ability Overgrow, which boosts the power Grass moves 50% when at one-third HP or less. With an Overgrow boost, Meganium's Sword Danced Seed Bombs with hit harder then Leafeon's Sword Danced Leaf Blades.</p>
<p>The EVs are rather obvious for a sweeper of this style. Adamant and maximum Speed places Meganium at 259 Speed, enough to outrun even maximum Speed Swellow after a Salac boost.</p>
