Well the spread itself allows you to not be 2HKOed by Landorus after rocks. The speed EVs though let you outruns skarm, loom, champ, cb tar. Kinda slow and it doesn't do very much but the primary idea behind that set was so that Politoed would stick around longer.

When you rated my team, you said to give Politoed a new that included 40 spe evs. What do the EVs do?
