How to get a Flareon?

Lol last lucky egg evolve I got:
1x Jolteon
6x Flareon IN A ROW
1x Vaporeon

There's the name trick, usable once per type (ie, you can name trick one each Flaron, Vaporeon, Jolteon, Espeon, and Umbreon). After that, there is no way to guarantee a flareon

Change the Eevee's name to Pyro, then evolve it.

The answer is to really, truelly, WANT Jolteons.... Then you will get Flareons.

Put your phone in a bag of rice.

Just luck, only that

There's a trick your phone checks the degree weather your in when you evolve, if it's over 90 degrees you get flareon. Hold a lighter to your phone while you hit evolve, and you get flareon
