Here are some of my thoughts on the Professor Video.
I don't believe that the Splinter Twin banning caused
Modern to fall apart. That thing was something independent that WotC decided to do; change their philosophy on Modern. Infect may have been able to survive a banning if Twin was not banned, but everything else needed to be banned, regardless of another powerful deck existing. Also, WotC has shown their distaste for Gitaxian Probe and that they had been looking to ban it for a while now, so I doubt that Modern would have been able to keep that card.
Twin and Summer Bloom were both banned. I was really upset at the time, more so upset about Summer Bloom being banned for a few reasons - 1, I hadn't played it as much as I wanted to since there were many other decks that appealed to me and 2, many players overestimated the Titan deck (saying, oh it wins on turn 1 all the time, while showing on camera that they don't know how to play against it). I personally think that Amulet at the time was a deck that nobody sided correctly for. The only card that was in the SB for Amulet was Blood Moon and Blood Moon would have been in SBs even if Amulet didn't exist, just to combat other decks. It was a very useful card. But I do see the Summer Bloom ban as an important one if they want to tone down the power of Modern.
Flash to nowadays. WotC keeps pushing cards like Oko, Underworld Breach, Emry, Uro, AA, War of the Spark PWs, and more. I agree with idSurge that if this is going to be their new design philosophy, it is a JOKE that certain cards remain on the banlist. Why can't I play Green Sun's Zenith if every opponent has Lurrus as their companion? I personally did think that the Modern meta was becoming stale at the time. Affinity, Twin, Jund, Tron, and Burn. It gets boring playing against those all the time
and not seeing many new, cool decks. But is the alternative a meta changing completely (having a rotation) every single MTG set that comes out? I hope not because if I had to choose between the two, I'd stay with a stale format a bit longer. I prefer in the middle, leaning more toward the format being stale (I like maybe 5 new cards and maybe 1-2 new decks coming out each set at most). It's hard to keep up.
If I am Spikey McSpikington that always has to play the best perceived deck, I don't want to switch decks in Modern every 3 months constantly. It's just not sustainable and to add insult to injury, there's cards on the ban list that are far more innocuous and obviously less powered than newer cards. That being said, Lurrus of the Dream Den
is certainly going to get banned. My first thoughts when I saw the card? Wow, this is powerful. I want to buy this card and play it. Then I think, oh %$#%, it will get banned soon or worse yet, WotC will ban all the pieces around it so that it is mediocre. Okay, I made my decision. I'm not going to play the decks that wins. I will not buy it. Is this the mentality that WotC wants players to have ... every new set that comes out?
