Yeah that flavor text is a perfect example of decent flavor text. Its a common among commons - everyone has seen this card before. You probably have 50 copies from various sets, so there's no harm in having a bit of fun with the flavor text. The humor is dry, but that goes perfectly with how its related to the Azorious guild. I'm not saying that this is anything special but it all works together nicely.
Then you have something like
Its a mythic, so its supposed to be special. You should have your best, most impactful, or funniest flavor text on these.
What emotion is this supposed to convey? Horror? Black comedy? I can't tell. I'm not a writer (I fucking hated writing and grammar in school) so I probably couldn't do better, but I can tell when I step in horse shit despite the fact I'm not a horse.
It's not even like I cherry picked this card because it was an example of exceptionally bad flavor text. I was just looking at the set in order, and this was the first mythic rare. I skipped over some other gems like
“It would be folly to fight a dragon engine head-on. Let’s hit it from above.”
and
“One down, several thousand more to go.”
By the time I reached the 8th card in the set, I found
1 card without flavor text
4 cards with annoying flavor text
3 cards with unexceptional but inoffensive flavor text
Frankly, the set made me wish they'd go back to two or three-set blocks, because I'd gladly take it being split down the middle rather than fucking New Capenna or Neon Dynasty. Well, or ONE now.
I'd love a return to 3-set blocks, but I'd even settle for the Big Set-Supporting Set style blocks too. I hate jumping from setting to setting.
While I'm really interested in the cards from MAGIC THE GATHERING: INFINITY WAR: ENDGAME: REVENGENCE, I can't wait for us to be done with this lame ass Avengers copypasta.
