I doubt someone would use it, especially for that cost.

yeah, it's the typical sidedeck card. but we don't have sidecks.

card for all who don't like "overpowered" Undeads :)
maybe little funny concept ;)

Maybe if it were replace with lower rarity, I would buy it. And still somewhat too specific, and same time too narrow.

Do you remember old Corrosion cloud? That card could just waste Unliving hand. It had Nature keyword that is stronger than Illusion. And it still was in 10 worst commons list. Another example is old Elementalist that became kinda useful only when got Banish and less hard-to-achieve condition.
Undead keyword already has a counter - Holy. The worst keyword in game when not facing Undead deck. That's enough.
OP Undeads and Undead supports don't need a counter, they need a nerf. Especially that ridiculous Crypt.
