>>40867840>you can lose track of your EVs easily outside of the bread and butter 4/252/252.Depends on method honestly, the "trick" is fully EV train BEFORE having a single battle if you gonna do a "complex" spread and that is something that people been able to do since XY, there is also the method of using EV-reducing berries to reduce into what you want FROM the max using those berries.
Basically, the trick is setting up so you have all reasources and can manipulate into the value you want from the ones you 100% know is there right now (No EVs or Max EVs).
Honestly there are so many tools for EV manipulation that this probably won't impact much at all.
