Mind Parasite

Hexproof
Whenever an opponent casts a spell, that player reveals a card from their hand. If that card
doesn't share a card type with the spell being cast, Mind Parasite deals 3 damage to that player.
"Fascinating. An entity capable of entering one's mind to feast on the knowledge within. I thought I was the only one around doing that."
