The real answer is...
How much do you want to improve and how important is money to you.
Its like people
that are self taught instrumentalists vs people that have had lessons.
that learned do snowboard from trial and error and people who enrolled in expensive ass lessons.
that learn diet/lifting on their own vs people that used personal nutritionists/trainers.
Someone that is short on cash will tell you hell no. someone that is rocking inheritance money may say hell yes.
Someone that is short on time will say yup. someone that has hours of free time to research game theory will say nope
Someone that cares a ton about the game and their improvement will say "lets do it". Someone that is casual with other priorities [other games, other hobbies, other obligations] will say "fuck no"
Noone is going to be able to give you an answer unless they personally know you.
----------
Of course paid coaching by a proper person [not a good player but someone that is a good coach, there is a difference] will help you out. Nobody can debate that. The only question is can you find the right coach and how much are you willing to spend.

If you think about hearthstone as a hobby. How many people get golf/skiiing/wakeboarding/voice/instrument/language lessons? people get good with and without coaching. it just depends on your personal evaluation of what matters to you + how much money can you spare. Some people can afford 200/hr lessons from a pro some people cant; some people care enough to spend 200/hr for lessons, others could care less and learn it themselves.

If you have Thunderhead on board you can play Voltaic Burst + Fire Fly to get a board full of Legendaries. Or if you doesn't have any minions before you can get atleast 4. I think it could turn out better than it looks.

All the cheap Shaman spells could chain up nicely with Auctioneer.
