Turns out, they said on another post that implementing [[Gutter Grime]] changed the way the game checks names. This must mean that Crowbar's activation tells the game to sacrifice (name) and for some reason the game thinks the name is everything you control!

Yeah, that's pretty much it. Because of a bug (introduced by Gutter Grime), the sacrifice part of: Equipped creature gets +1/+1 and has “{W}, {T}, Sacrifice Citizen’s Crowbar: Destroy target artifact or enchantment.” Lost its reference to Citizen's Crowbar, and the rules engine decided it meant sacrifice All The Things.

The Arena rules backend works by basically reading the cards (natural language parsing), and we have to regularly adjust that reading process to make sure it understands new cards properly. In some cases, like this one, that can lead to older cards getting new (and improper) behaviors. We have a lot of automated and manual testing to check for this, but with ~8k cards there's always the possibility that something sneaks through.

In any case, we're working to get a fix out soon. Until then, I wouldn't recommend sacrificing Citizen's Crowbar (and your whole board).
