[SET COMMENTS]
<p>Though Clefable is usually defensively-oriented, this set allows Clefable to strike hard right off the bat to break down walls. Double-Edge is Clefable's main form of attack, 2HKOing Clefable, Lanturn, and Hypno. Fire Blast tears through Steelix like a baked potato through snow, dealing a minimum of 91.52% to standard (252 HP / 132 SpD) Steelix. Fire Blast also 2HKOs Venusaur, Weezing, and Rotom (among others), while OHKOing Leafeon and Scyther. Grass Knot will always 2HKO 252 HP / 0 SpD Claydol; OHKO Omastar, Kabutops, and Relicanth; and 2HKO max HP Aggron.</p>
<p>However, what sets this apart from other UU wall breakers such as Sharpedo is its bulk and Softboiled. Most walls switching in will have a lot of trouble breaking past those 331/182/216 defenses, and most UU walls lack a recovery move, so Clefable will be beating most walls even if they predict properly to get in on a non-damaging move. For example, let's look at some calculations against 252 HP / 252 SpD Calm Venusaur. Its strongest attack against Clefable, Sludge Bomb, can only muster a maximum of 38.08% damage. Meanwhile, Clefable will be hitting it for 52.74% damage minimum with Fire Blast, and Double-Edge causes 52.19% damage minimum, so Clefable will always be able to stall it out by cycling between Softboiled and Double-Edge or Fire Blast, even if Venusaur comes in on a Grass Knot or Softboiled. Other common walls, such as Steelix, Claydol, and Lanturn will not be able to 2HKO Clefable with their standard movesets and lack recovery, so they too will usually lose to Clefable on the switch-in.</p>
<p>68 Speed EVs are to outspeed minimum Speed Weezing, which can allow Clefable to knock it out with two Fire Blasts without getting burned. 216 Attack EVs ensure that Double-Edge 2HKOs 252 HP / 0 Def Calm Clefable. The rest of the EVs are placed in Special Attack to maximise the damage output from Fire Blast and Grass Knot.</p>
