It's true there should be variant REDEMPTION levels. Some could be -1 and it wouldn't be as bad. Some higher mana ones could be -2
Or it could get -2 at max level card... that way it's really only played in champion leagues.

Interesting idea, but wouldn't this be a glaring exception to the current consistency of abilities across all leagues?

I agree, and mentioned this some time ago.. too powerful and now there's more of them. I dont see it too much in the mid-levels but I guess the Slimeball card is showing up a lot in Champions?

yes, especially for low levels it is super powerful, i was happy that death got some revival like this but now... :-(
