I should probably wait but there's no data on hsreplay for big spell mage.  Trying to get advice and see if I can perform a little better than 52% win rate. I think there's a place for big spell mage with everyone playing wide and polymorph being good against priest. I suspect that I'm probably being to greedy with the end game but figured I'd make a thread just in case that is incorrect.

Thanks for suggestions in advance.

I think you need to get even less greedy than that, maybe run explosive sheep doomsayer or other early game board clears. I'll admit I'm no expert on big spell mage but those seem like the things this list is missing

You are gonna get murdered by big priest and the new big warlock

Mage cant beat big priest without kazakus 

I don't know how good mage in Wild, coz i ve not seen any big spell mages here, only burn, otk and quest. Control in wild doesn't exist in typical form, all control will be f*ed with super greedy druids and your Elysiana doesn't saves you. A lot of combo decks, a lot of aggro, a lot of really game breaking stuffs, fair control is bad.

If we talking about fun, that's mean you can out all your 2 drops, coz they are not so needed and add Keleseth, Keleseth Big Spell mage is the best in standart. in wild, i think too. -2 oozes +1 3 mana ooze, Arugal is too greedy, you need cards not for win more when you wining, but for your early game, 1-4 out of my jungle will be fine or if you met a lot of aggro 1-5 Tar creeper. -2 ravens +1 or 2 acolites. 

Problem with Keleseth - Khadgar, i m 100% sure, you want new deck, not just typical big spell mage, and for the great fun, you can play with 2 drops, but still, oozes bad, 3 mana is better for control and Arugal super greedy.

Another part,  giants is from different archetype, coz it's just slow 8-8 do nothing you are not warlock with his hero power and you not using conjurers thing that's makes you 2 giants or 4. Giants awesome, coz warlock can put them on turn 3 and it's insta win for them, if you just droping them in late, it's meh card

I m 100% sure you need meteors as another removal, coz you have only 2 poly. And you need board presure with some minions, in standart Mages used 4-4 elementals, 1-4 turttles, 4-5 tree and other things, in wild i think, you can use belcher, new 5 mana girl who can deal 4 damage for your big spells. Also, i think, Malacrass is bad, slow and gives you not so much, syndra is better or you can use Medivh, has value and Lich king also still great, Dr. Boom has synergy with Khadgar and Frost Lich Jaina.

TLDR don t be so greedy for fatigue, go for value greed, fatigue is part for War and Druid, you will lost vs them here and vs Priest you don't need extra anti fatigue - coz of Scream.

If we talking about wr and not fun - go for odd mage, it has potential in wild too. But it's not pure control, i know.

It depends of the ladder rank you're in. I don't think "classic style" control decks can do it beyond 10 in wild. I'd say you should have some plays to try out, but I'd personally prefer a reno deck or a more powerful late game.

big spell mage is very bad in wild..

reno mage is the far better archetype

I've been having success with the deck in description, reaching rank 5 consistently was easy peasy, at least before RoS, dunno how good it is now since I've been trying different stuff. I try to outlast everything my opponents throw at me with the help of Jaina, N'Zoth and all the AoE. I have Dirty Rats for combo decks and a big combo against control. The combo is Thaurissan: Brann - Jan'alai - Zola + eventually Echo of Medivh.

BSM was bad in Wild before, and it didn't get any serious new tools with RoS.

The only Control Mage in Wild is Renomage.

You can still try ofc, but without great expectations. 

Moreover, your list is just a Standard Raven BSM, with some RoS Value cards: you need major changes if you want to have any chances in the meta.
