And once it's on board, it rarely stays small for long
Uncommons & Commons Invasion of DominariaInvasion of Dominaria Four life and a card is not great for three mana, and five defense is a lot to go through, but I don't care
In my experience screwdowns have too much space in them and have a higher risk of damaging the card then toploaders/softsleeves
Anyway, the card is also just as important for Zombies as Champion of the Parish is for Humans, especially when you consider that where Humans uses Thalia's Lieutenant to double-dip on counters on turn two, Champion of the Perished can actually combo with Lazotep Reaver to do the same
Mechanically, a traditional "split" card, like this one (which was played by Pro Tour Champion Kai Budde in the greatest Pro Tour Top 8 of all time) is practically / thematically very similar to both cycling cards like Go for Blood and many Modal Double-Faced Cards
