Many Orc cards work best when used in conjunction with other Orcs, and the Bangkorai Butcher is one of the best examples of this. Played by itself or with a non-Orc, it is moderately powerful, but there are other Might cards for the same Magicka cost with better stats. When the Bangkorai Butcher joins another friendly Orc, on the other hand, you get a 6/5 creature for just 4 Magicka, making the Butcher a must-have for any serious Orc deck.
If drawn early in the game, it is best to wait until you have other Orcs on the battlefield before playing Bangkorai Butcher. Alternately, if you have no Orcs on the battlefield but have enough Magicka, play this card immediately after a low-cost Orc card. When used in conjunction with other Orc cards, such as the Wrothgar Artisan or Militant Chieftain, or when buffed by a Soul Tear or Warrior's Fury, the Bangkorai Butcher can quickly become a formidable creature.
