That's debatable. It's like you guys are having a bad-removal off lol
Man, I sometimes forget you only do power maxing lol
In lower power formats the threats aren't really capable of exerting the same type of pressure they are in your format. When your creatures start to be a guaranteed double spell, removal has to be ultra-efficiently costed to allow the answering player to keep pace in spell castings. When you have a bunch of creatures that are giving a guaranteed spell effect regardless, and are removal checks in themselves, removal needs to be as unconditional as possible. This is due to the game becoming progressively more tempo and threat focused.
When your format starts to run lower power threats with a focus on activated and triggered abilities accruing value over turns as part of an engine, you can start diversifying your removal, which creates the turn gaps you need for cards like that to do anything.
As you noted, thats probably why we got an anecdotal instance of sandwurm doing something.
However, the removal should still be reasonable, with very light conditions attached, though I am sure from your perspective anything that isn't path to exile, swords to plowshares, or toxic deluge probably looks like
lash of the whip.
I've ran formats with actual, deliberately bad, removal intended to open up space for board state building, and even in that format, once you get over 6CC, if its being hardcast, it had better come with an ETB or some similar mechanism to compensate for being hit by interaction. A player is investing their turn into that type of play, and almost
any interaction that interferes with that type of investment is devastating.
Though thats only part of that cards problem, the other part is that my top end threats (and his) soundly outperform a vanilla 7/7 for 7.
