How to Get
This card can also be obtained from Card Packs. Diamond Chests and Card Packs can give Premium versions of this card.
Works well with Infiltrate units, and units with high attack. Probably best to only run in a 2 color deck, and not a 3 color deck due to the restrictive casting cost.
Nightmaw's ability includes Nightmaw as well.
