japanese haunter pokemon card No.093 Vending Series 3 Haunter AR 022/021 MBG Starter

Its possible Merfolk still wont have what it takes to be a top tier Pioneer deck, but Cenote Scout is a large upgrade, nonetheless

It has been in nine core sets ( Sixth Edition , Seventh Edition , Eighth Edition , Ninth Edition , Tenth Edition , Magic 2010 , Magic 2011 , Magic 2012 , and Magic 2015 ), two beginner products ( Portal and Starter 1999 ), two normal expansions ( Tempest and Odyssey ), and five supplemental sets ( Beatdown Box Set , Planechase , Magic: The GatheringCommander , Tempest Remastered , and Eternal Masters )

Silent-Blade Oni

While that wont happen that often in casual EDH, its good to have the bonus

The only other such card not in Unglued or Unhinged, or Unstable (Magic: The Gathering), or any other joke set was Falling Star, from Legends
