Nice card. Here are a few more non-playtested variations on the theme (with the last one being a potential alternative).
Witch Doctor ($4 Action-Attack)
+2 Cards
Each other player gains a Curse, putting it in their hand. Any player that did may set aside a card from their hand onto their Witch Doctor mat. Return the set aside cards to the player's deck at the end of the game.
Summary: a Witch that doesn't clog up your deck. The victim may choose to set aside a non-Curse (or nothing) if they want to try to trash the Curse later.
Inquisitor ($4 Action-Attack)
+2 Cards
Each other player gains a Curse. Any player that did may discard an Action or Treasure from their hand and, if they did, put the Curse on their Inquisitor mat. Return the set aside cards to the player's deck at the end of the game.
---
Any player with cards on their Inquisitor mat at the end of their Cleanup phase may discard an Action or Treasure card from their hand. If they do, then trash one card from the mat.
Summary: two-stage Torturer-style attack. The second discard is after Cleanup to provide some protection from further size reduction attacks.
Extortionist ($4 Action-Attack)
+2 Cards
Each other player gains a Curse, setting it aside on their Extortionist mat. Return the set aside cards to the player's deck at the end of the game.
---
Any player with cards on their Extortionist mat at the end of their Cleanup phase must either:
- discard at least one card from their hand; or
- discard all the cards on their mat.
If they discard from their hand, then trash one card from the mat for every card discarded after the first.
Summary: a postponable Torturer-style attack and closest in style to the original card. Curses don't get trashed automatically to provide play incentives for the attacker even when the 'ransom' is paid.
