How to survive Dwelves and current Siege?

So, in last 2 months i have huge problems with one particular deck: Dwelves. Playing like 9-10 months, got to pro every single month except for Nekker meta (was bored and quite busy), totally into game (watch many streamers, learning some tactics and quite interested in meta), so not complete noob. But get smacked almost every time i meet this lineup.

Same goes to new siege with generator. Early i was able to counter their engines, but now it's quite hard in 2nd and 3rd round cause machines starting with 6-9 base power is likely requires some hard removal or lock. Overall, i feel like first is quite overtuned – too many uninteractive strong cards like Censer. Don't mind about Siege, still can't get reliable strategy to beat it.

I prefer to play homebrew greedy engine-based decks, so it's obvious bad matchup, but even with some more popular meta-decks i'm struggling with dwelves.

Any words of wisdom?

P.S. still, meta is great and quite diverse, but it saddens me how difficult it's to play against complete board onslaught and later pointslam like Henselt-Pride or Simlas into waylays.
