This is, to put it mildly, poppycock. These are the decks for Grandmasters 2021 Season 1 Week 1, which was 9 weeks ago (as opposed to 4 months):
NoHandsGamer:
Control Priest, with Spellweaver Malygos and C'thun
Watchpost Rogue (Remember Watchposts? They got nerfed. Good times)
Libram Paladin, with Taelan Fordring and Penflingers (Remember Penflingers? They got nerfed. Good times)
Spell Mage, with double Flamestrike, and only 1 Ring Toss and 1 Combustion, and 1 Cone of Cold?!
Thijs:
Control Warlock (Remember Warlocks? People thought they were good once upon a time. Good times)
Watchpost Rogue (see above)
Libram Paladin (With KAzakus in the list, even though there's a great risk of having him be disabled due to Libram Discounts. People thought this was a good idea at that point. THIS DECK HELPED WIN THIS WEEK)
Spell Mage (Thijs version runs actual secrets instead of Ring Toss, bless him)
Alutemu:
Watchpost Rogue (again, see above)
Control Priest (With Ysera as it's only win condition and relying on spell generation otherwise. It also runs a natural Shadow Word : Death. People did this back then. AND WON.)
Libram Paladin (see above)
Spell Mage (Double Flamestrike and a natural ICe Barrier. No Ring Toss in the deck. At all.)

And even the most the same deck, Spell Mage, saw crucial differences in how the deck is built. (also, only 1 Spell Mage this week that actually won, compared to Week 1 Spell Mage (that was with Deck of Lunacy at 2 mana. Remember that? It got nerfed. Good times)

weeks 2 until 7 has a cap of 2 packs in total, playoffs have a new 2 packs cap
2
for 80/100$ or 10/12k ????
3
Maybe try a deck which needs some thinking
2
Also could add amalgam, nice taunt body and extra minion for nzoth
2
is tai actually needed?
1
51 no pass only play 3 times a week
-8
just make lunacy 6 mana, keeps te ultimate meme alive if u topdeck after turn 6 but also kills that turn and dead card in the first turns
2
Horrendous Growth should probably be cut, same goes for noot (what destroys the quad god) but i think you need more early game in this deck or extra stall like khartut the 6 mana heal or 6/6 taunt and stuff like that
1
look like a lot of fun
2
this would actually be great if blood herald was a beast... with rhino a nice win condition added
