@jaydabbler and I'm just playing devil's advocate here, just spitballin'.... while i understand jester is an effect of the card and not from them playing tricks, and while i wholeheartedly agree that changing the mechanics would break other cards; i do feel sportacus is outclassed by both jestster in damaging the hero conditions, and def end (especially with gargologists) in the defending against tricks conditions.
I think the easiest fix would be putting 1 shield on him. This would at least defend a bit against common tricks giving a bit more longevity.
While the card has brought me a little success, the main thing I've found it useful for is taking the hit for another card I've played. That's still a great use, but there are better 3 cost cards to run, imo. There's nothing about it that makes me value it over BeP, for sure.
Not only that, but most importantly... with a shield he would actually match his design!
