I’m not a Vanar main so take what I say with a grain of salt or at least until other vanar mains chime in.
The biggest problem I see in trying to make this deck work is that this is not an inherently bad deck but that Vanar has enough ramp to play some way better late game cards. And if they don’t draw them, they can usually survive with removal utility minions.
With your deck, you can certainly ramp out these golems easy enough, but compared to playing a card like Ice Age/Emble on turn 3 followed by a Wall’s Wake is much stronger.
And this is not to mention certain card’s absence in this deck the most notable being Malicious Wisp.
EDIT: I feel a bit bad to completely dump on your idea, the best advice I can give is to just take this deck and try it out on ladder, see what needs fixing or if its just altogether bad. This is assuming you have the skill to reach diamond with a decent deck. If you are still relatively new then you should try to learn to play the game a bit more so you can know what makes this deck good or bad.
