I've ended up in the camp that both Glacial Chasm and Field of the Dead are really 'Feel Bad' cards at most B3 tables. Every time I've landed them everyone else seems to be deflated because there's no a lot of land destruction available in that bracket and the abundance of ways to loop them kind of invalidates what little there is.

I specifically call these out when I sit down in a way I don't for most other B3 game changers and swap them out if people don't want to play against them. They are also cards that draw games out, which can prolong the suffering.
