How to use a Lucky Egg effectively
I have posted a few times about how to use a Lucky Egg effectively. I wasted my first Lucky Egg before learning this so I figured I'd write this post for everyone. Especially since I have the benefit of having played Pokmon games since the late 90's.
First off, if you don't know what a Lucky Egg does, it doubles the XP you receive for 30 minutes per egg. This is much the same as the Pokmon games for Gameboy/DS, however in those games Lucky Eggs are much harder to come by and only effect the XP of a specific Pokmon.
So doubling all XP for 30 minutes is great right? Well you'll want to get the most XP for your time, I'm posting this because after doing this I achieved nearly 55,000 XP in 30 minutes. Yes, 55,000. Almost 60,000 however I was off by a minute. I'll explain that soon.
First off, are you tired of seeing Doduo, Zubat, Rattata, Pidgey, Caterpie, and Weedle? Perfect, catch all of them. Why? Because you see them everywhere, and Pidgey, Caterpie, and Weedle are your best friends for a Lucky Egg. Doduo and Zubat require 50 candies to evolve and are the most expensive of the bunch to evolve, good thing they're everywhere. Rattata needs 25 candies to evolve, much more reasonable. And Pidgey, Caterpie, and Weedle need only 12 candies to evolve. This an XP goldmine.
For best results you'll need to do some math. For starters, catching a Pokmon gives you 3 candies for that Pokmon. Transferring them gives 1 candy. So having enough candy to evolve 24 Pidgey and transferring them allows you to actually evolve 26 Pidgey. This is what you're looking for. Basically to make use of your 30 minutes you'll want to have 50 or so Pokmon you can evolve.
Secondly, egg hatching. What you want a numerous eggs with the same km rating. You want to put them all in incubators at exactly the same time. This is where I messed up, I was a minute off on my egg hatching and lost out on about 5,000 XP. If you have 9 eggs with the same km rating and don't mind spending the money to buy egg incubators this will greatly benefit you. You put all your eggs in the incubators at exactly the same time and get them to about .01 or .02 km before hatching, however only do this step after you've gotten all the Pokmon you want to evolve.
Here's where the mass XP gain comes into play. You have your 50 or so Pokmon with enough candies to evolve them ready and your eggs are about to hatch. Use your lucky egg. Now evolve all of those Pokmon and transfer them until they are all evolved, if you already have the evolved forms of these Pokmon you get 50,000 XP in evolution alone. Add an additional 2,000 XP once for every Pokmon not in your Pokdex that you evolve. Now, with your remaining few minutes, hatch those eggs. That's an additional 1,000 XP for every egg hatched and again add an additional 2,000 XP for every Pokmon not already in your Pokdex. In 30 minutes with the Lucky Egg you should be able to achieve roughly 50,000-60,000 or more XP. Happy catching.
EDIT: FIXED A COUPLE NUMBERS IN MY POST
Here's some proof, sadly I missed the screenshot of the 48,000 XP I received from evolutions.
