I have edited the post and added some extra suggestion at the bottom, just above the stats screenshot.

So because I am not a fan of control decks I've been playing this secret mage. I play this one currently but from time to time I switch 1-2 cards. Also just as a note, I am just a casual player and I play only mage :)

Last month I came back into the game after 1 year and a half of break and I crafted a mage deck based on secrets with which I pretty much advanced from 25 to 8. I would've probably advanced more but I started playing in the last 5 days of the season.

This season I played another variation of this deck, a bit different but in the same secrets league, and managed to get to 12 so far (after I reached 15 I went trying different mage decks, more control decks, but ultimately I came back to secrets and crafted this one recently. 

I play pretty much only mage, just cause it's my cup of tea. I have uploaded on Youtube a few videos with a variation of secret mage so you can get an idea. Those videos are from last month's season and I still have to upload more since I reached rank 8 with my secrets deck, I just hadn't had the time to put up all the videos I recorded.

Here's the playlist with those videos. You'll find videos from 17 to 13 and probably tomorrow I will upload the rest of the videos 'til rank 8. 

Here is the link to all the existent videos, to the playlist with some secret based decks

and below is the first recorded video.

UPDATE

Had some time and I managed to record a some gameplays using this deck. I will probably record more in the following days while I'll have some spare time from work. You'll see plays against druids, priests, mages, a warrior, a pala, as far as I remember :) Check it below:

 

You will find below a screenshot with the current stats for this deck. The druids I beat were playing Jade so that's that. I just hope it can help you out guys. It's 10 games but still. All those 10 games were played starting from Rank 15. 

Also, just a couple of things:

1. Regarding Yogg - This is a great card in this deck, it saved me a couple of times, it filled my board with minions every time :). Until you put him down make sure you play as many spells as you can, you have 17 spells + 2 from PG so that's that.

2. Regarding Medivh - People tend to play this only if they have big spells in their deck but in this deck it works like a charm. The idea here is to use your spells and fill the board thanks to its mechanics. Most of the times I end up using Firelands, Fireball, and some spells from the Primordial Glyph if the cost is at least 4. 

3. Regarding Pyroblast - Many times I end up taking the other person below 10 or at 10, and Pyroblast is top notch.

Another simple suggestion, go face as much as you can. You have removals, use those, and just hit the face. Normally the deck can take you in ultra long games and you can win, but it would be a good idea to not want to do that. 

If you will watch the videos I shared you will see that with a similar secrets deck I won really, really late. You can also replace one Mirror Entity with another Frozen Clone. It might cut a bit of speed but you will have 2 extra minions in your hand for those late situations. So with 2 Frozen Clones + 1 Mirror Entity you can get 5 extra minions.

I had a couple of games that went for 20 mins and I still won, just check my videos :)

In my opinion you have plenty of things in this deck. You have 17 spells + 2 from PG, you have 13 minions + 4 from Frozen Clones and Mirror Entity + 1 from Firelands + 3 from Medivh + whatever Yogg gives you. 

If this deck helps your game, feel free to upvote it and if there is interest I can give more suggestions.

I will most probably build/test other decks and most probably those will end up on Youtube so if you want to be updated feel free to subscribe

Cheers and much love !

EDIT:

People are asking what to change Yogg with and the answer is rather simple, there isn't anything like Yogg but we can add another card that might go well with the deck.

Here are some of the options:

1. Arcane Giant - it's always nice to play an 8/8 with a low amount of mana, depending on how many spells you used. I would suggest to lower its cost as much as possible so that you can play other cards as well in the same turn.

2. Ethereal Arcanist - this might also be good, it has 3/3 and at the end of the turn it gains +2/+2 if you have a secret; so for things to be 100% sure, I would suggest to put him down only when you have an active secret. Don't do something like, "I will put him down now, and next round I will just put the secret".

3. Avian Watcher - Normally has 3/6 but with a secret on it will gain +1/+1 and Taunt

4. The Black Knight - for all those nasty taunt situations, plus it will save you 1-2 removal spells which you can use in a different way, face maybe :)

Other suggestions:

If you want some more minion power for late games, you could remove 1 Mirror Entity and add another Frozen Clones. I would suggest to keep those 2 Counterspells, don't remove any of those.

If you feel like you don't need 2 Arcane Intellects, you can remove 1 and maybe add an extra Firelands Portal (gaining an extra minion + 5 dmg).

Now you have 2 Volcanic Potions. You can also keep 1 Volcanic Potion and add 1 Flamestrike, that depends on you and your needs.
