Definitely a sus list. Most of your observations at the end are correct. Bad mana base, bad maindeck choices, bad sideboard choices. The Goblins Discord would shame this list.
It's sad how modern has gotten these days. Modern Horizon sets were a mistake. The only real reason to like the Modern Horizon sets is how they lowered the enemy fetchland prices and maybe bringing counterspell to modern, but everything else was a mistake: -Hogaak -Evoke elementals -Ragavan -Force cycle
This take is just a regurgitated cringe take. U shouldn't judge sets by their worst cards. Both mh sets made a lot more decks viable and better aswell as creating totally new archetypes that are rly fun to play. If you think MH is a terrible thing still you're probably just a disgruntled boomer commenting on every MTG video you see saying this.
