There is a whole community / website for mixing (mostly) metal called URM. Basically, it's a subscription service where you get the original tracks from a song from a pro band at the start of a month, have some time to play around with them on your own, and at the end of the month, there is a live session with the original mixer mixing the song step by step in a 4-10 hour streaming session. So you can basically copy every move (if you have the same plugins) and end up mostly with the same "sound". That's where I got most of my mixing skills from, basically learning everything directly from some of my favorite mixers. So thank you, internet 
Surprisingly, most of those mixers use the same plugins that we have in our toolbox (Waves, Slate, Fab, that kind of stuff), with some of them even do the unthinkable and use stock plugins. On top of that, everyone uses their own kind of preferred samples for kick, snare and toms, and that's it.
Yep, that's it. When you watch those sessions, you slowly realize that the sound from the record was already there from the start, and most of the time the guy on the screen only had to make small eq moves, cuts, boosts, and a bit of automation to make the tracks sound exactly like the mix / song you hear on the record. It's not the studio, the nice speakers, the well-treated room. It's well played and recorded tracks and the ability of the mixer to not mess too much with the original sound, just to enhance it.
And that's where a lot of people fail, because they think they have to make drastic EQ moves to make something sound different than it was recorded. That they have to cut X Hz because that's what Big Pro Guy said in a video, totally ignoring the fact that every recording is different and that you can't apply the same settings to the rhythm guitar all the time.
Sure, you probably have to enhance the original drum sound with samples, because it's hard to get THAT sound everybody is looking for without them. But in the end, it's mostly the same kick and snare samples over, and over again. Why? Because they just work. Here is a great video from Rick Beato showing how Andy Wallace basically uses the same kick on different records: https://www.youtube.com/watch?v=F916ioSWdts
For a start:
Here is a good video on how to get the bass pinned in the mix: https://www.youtube.com/watch?v=00kI0Ashqp8
You can (and should) use a similar approach for the rhythm guitars: At the end of the mixing chain, put a limiter on each rhythm guitar track, limiting the volume so almost every hit gets affected. You are now basically pinning them to a certain volume. Together with the bass, you can now create the typical "wall of sound" that stays consistent throughout the song by just balancing the rhythm guitars with the bass. You don't need dynamics on guitars in metal anyway, and if you want movement, use automation and add movement (aka volume changes) to make a part more exciting. You will instantly notice how big this will sound.
For the rest of the mix, Nollys Tutorials are great to understand how you mix this kind of material.
