So you did hit legend with this deck and you did dominate mage ? Not you didnt or you got very very lucky and you did. Sorry for being a dick but the thing is while I appreciate someone's enthusiasm, posting a deck and claiming big things without any prove is bad. 

I tried this deck and it is just terrible and I will explain why. Also I played most of my games versus mage on legend rank and got destroyed. 

1. Zarimi is a strong card and it is easy indeed to get her activated like you claim however most of the times you end having an active Zarimi in your hand and you cant play it because as you say it is strong when you play it on the same turn with a Cheese or Ignis. This situation is very specific and is very rare especially when you consider that you have 40 cards in deck and you cheese needs to be many turn in your hand to summon big minions. Zarimi works in a normal deck because you play it is the same turn with bunch of zero costs minions. This is not happening in this deck so most of the times it is useless card. Imo if you want to play Zarimi then you need to build your entire deck around her.

2. Because you have Zarimi you include these cheap dragons which again are strong in the original Zarimi deck but suck in this XL deck. 

3. The hero power package is just 2 useless cards. I tried to build a deck around this and make this work but this is not working in the current meta with so big health and armor. So what happens is you have these 2 weak cards so you can play them in the same turn and do a lot of damage but not only the condition is very hard to achieve as you have to play Raza and Reno, but also when you do manage to get your combo the best thing you get is using your reno hero power 4-5 times and you will not get even close to kill someone most of the times.

4. Last but not least. You do have 40 cards and you are saying that there is no place for a Puppet Theatre ? I dont know what to say about this. Even if you still want to play all these weak packages you could still replace half of other cards for the theatre which is by far one of the best cards Priest has.
