This champion is a good one, though a bit of a gambler. When in combat, the Beastmaster's player chooses one opponent (not nessessarily the one he is attacking, but often that player is a good choice). The opponent hold up all of his or her allies in hand, and the Beastmaster draws it and plays into battle immediately. Even if that ally could not normally be used by the Beastmaster (like Cult of the Dragon (80/DR)), the Beastmaster can use it. This ally is safe for the battle, being unable to switch sides or be discarded.
This power may only be used once per round of battle. Good cards to use with the Beastmaster include Rings of All Seeing (171/4th) (to see who has good allies) and Intensify (89/PO) (to double the level of the stolen ally).
After battle, the ally goes to its owner's discard pile, regardless of special powers. This champion could be useful in tournaments, when many instant win allies are used. However, since you may play against decks without any allies ready, it is a gamble many tournament players may want to avoid.
