two legends one piece booster box Piece: [OP-08] Case and the Animal Kingdom Pirates as black One Piece Trading Card Game:

Malicious Affliction Doom Blade is strong, but not as strong as two Doom Blades

shaving a mana from it with The Ur-Dragons eminence makes it quite powerful when it comes to casting discounted Dragons from the top of your library

Scar, Vengeful Lion will help with card draw, as every time you challenge an already damaged character, you can take the top card of your deck and tuck it safely into your hand

Creature - Druid Rhino Phelddagrif : Phelddagrif gains trample until end of turn
