pokemon card ghost C 034/062 [SV3a] Dead By Daylight Ghost Face

This human shamans a pretty cool mana dork, if a bit underpowered for a rare these days (I wouldnt be surprised to see it at uncommon in a modern set)

What are the weaknesses and retreat cost of this Swablu card

One such card could be Cecil, Dark Knight, which costs 1 Black mana for a 2/3 Legendary Creature with Deathtouch, but it arguably has a downside that is not necessarily its Darkness ability, but the fact that one can't have multiple copies of this card on the battlefield at once

Meek Attack takes the number one slot because it represents something I value even more in Magic: The Gathering : a unique way to play the game, wrapped in excellent flavor and memorable art
