it was removed because the set is no longer good in this metagame, but you can find some older breloom analysis threads in locked&outdated, such as this one http://www.smogon.com/forums/showthread.php?t=3458682
which lists the spread of
evs: 236 HP / 212 SDef / 60 Spd
<p>The spread might seem strange, but it does have its uses. 236 HP EVs will ensure that Breloom will have the highest HP number that is divisible by 8, meaning that it will recover the most HP from
Poison Heal. 60 Speed EVs allow Breloom to reach 191 Speed, outspeeding minimum Speed Heatran and other bulky Pokemon such as Choice Band Tyranitar, Skarmory, and defensive Politoed; the rest is put into Special Defense in order to take hits such as Rotom-W's Hydro Pump much better, as well as surviving moves such as Defensive Reuniclus' Psychic and Celebi's Hidden Power Fire.
