SOS Chaining is pretty good. Once a chain starts, you get a x2 multiplier added on to each EV you aquire from fainting a Pok?mon. This stacks with the x2 multiplier from Pok?rus, and Power items now give you an extra 8 EVs in a specific stat instead of 4 EVs. This means you can get a total of 36 EVs off of a Pok?mon that would normally give only 1 EV without those stacked effects.
wait really omg that's amazing
