Is tempo mage the most frustrating deck to play against?

I am talking about this deck: https://tempostorm.com/hearthstone/decks/tempo-mage-meta-snapshot-48

I find this deck extremely frustrating to play against because the entire deck is so incredibly full of RNG cards. #feelsbadman whenever every single one of the arcane missiles / flamewalker shots hits exactly what it needs to hit, or when they rip something ridiculous out of unstable portal. You can try your best to play around it, but the RNG nature of the cards makes it feel impossible.

Whenever I lose to this deck, I never feel like I got outplayed. They just got their lucky RNG roles that game. When I win, it never feels like I outplayed them, just that the RNG gods let out a wet fart instead of handing them victory. It doesn't feel like an earned victory either way.

I think the problem is that there are just way too many powerful RNG cards in the deck. I don't think it is a good thing if RNG cards are good enough to where you can play them competitively because too many of the games come out to who got lucky on one roll of a card vs. who didn't. What are your thoughts?
