I very much love the dinosaur ghost vibe and I wanted to try and contribute my own addition!
LEVEL 3 - DEIMOMUNCHUS
(UNDEAD): This card is undead.
(GHOST EATER): Once at the start of your turn, discard one ghost in play, then this card gains 1 Level. If there are no ghosts in play, this card instead loses 1 Level.
The name's pun is horrible and so is this creature! Do you have a bunch of ghosts gathering dust? Do your neighbour's ghosts bother you? Let this thing eat them! That's its whole deal!
