[SC] Most efficient way to build gates

Okay,so i know that this should originally be at "newbies" section but it is like a guide i want to make and see if it is any good.Then get feedback from other forum members so that way i can improve my guide and my way to build gates.Guide sample(draft):
The first thing you want to do is buy premium and rebate.Then collect some uridium.
1)Wait for an extra 25% extra discount from shop so you can get 55% overall discount(premium+rebate+shop discount).
2)Buy a pet.Do a lot of missions until it gets to lvl 8.Repeat step 1.Buy kamikaze gear.Login at important events like crazy cubikon and spaceball but don't bother pallying at 5-3 map because people are merciless and you are gonna die a lot unless you are in a clan with many alliances.
3)After you have collected a ton of uridium from crazy cubikon repeat step 1.That way you will spend 45 uridium for 1 GG spin,very cheap.Build zeta,finish it at double rewards day.
4)After getting 35k uridium from finishing a zeta at double rewards day,repeat step 1.Build another zeta(with the 35k uridium you got from the previous zeta) and finish it at double rewards day.
5)repeat step 4.......profit
Feel free to post anything that is relevant with this topic no matter how stupid it may sound.Feedback is appreciated.
Note:I also watched some videos from "terrorthelegend" the youtuber so i will give a lot of credit to him.

 

To point 4, uri is not doubled on double reward day so you get 35k uri and not 70k uri as you have stated.

 

But aren't all the rewards supposed to be doubled?

 

USS-Aries is correct as usual, and >here< is the official Post with each gate shown...
There was a longer time, until recently in fact, when Uri and x4 were also doubled, but DO did state early on that this was not intended... it just took them a while to correct it

 

A while... to "correct" it huhuhuhuhu...

 

Uridium was never doubled
