<p>With the specified EVs, Jolteon's Substitute will always survive neutral Hidden Power from 319 Special Attack (without STAB) in addition to other notable moves like Celebi's Grass Knot and Blissey's Ice Beam. The speed EVs ensure that Jolteon is slower than opposing Jolteon, allowing it to pass the Subsitute (nsc) while remaining faster than Timid Shaymin-s and most +1 Gyarados. Light Screen support is very welcome here to boost the durability of Jolteon's Substitutes.</p>
<p>Any Jolteon can serve as an intermediary switch to absorb Electric-type attacks or Thunder Wave, but this particular build gives Jolteon additional options to Baton Pass something useful. With such defensive EVs, Jolteon is a safe switch into Zapdos. Zapdos's build can be determined by the damage dealt by Heat Wave. If Zapdos's Heat Wave deals 26 - 31%, Zapdos is most likely neutral natured with 0 SpA EVs; if Heat Wave deals 35 - 42%, Zapdos is probably positive natured with max Special Attack. Jolteon can stall out the former by alternating between Wish and Substitute (nc) and Magnezone's Hidden Power can be treated the same way. It takes time to learn how to use this moveset effectively, but if you persevere, you will be pleasantly surprised by its usefulness.</p>
Those SpDef EVs guarantee substitute's survival against timid Jolteon's hidden power:Putting the speed at 244 means you always outspeed Adamant Gyara after a Dragon Dance. Do those 3 extra points in SDef make all the difference?

I'd add Discharge as an option next to Thunderbolt, because the 30% paralysis rate goes with the support theme. Paralysis gives the BP recipient an easier time to set up or simply just retain the Substitute.[SET]

(I'd change the title to distinguish from other support sets. Something with the word 'bulky' I guess.)

(It should be the primary EV spread, since speed brackets are absolute to the single point and small changes to defenses are negligible. Also, max Speed neutral Gyarados is the most popular EV spread in this ultra-offensive metagame.) Light Screen support is very welcome here to boost the durability of Jolteon's Substitutes.</p>
Shaymin-s is uber now, so remove the reference and recalcuate the speed EVs.
