Excellent card, when you need ally ASAP. And another good points is fact, that really costly ally (like 4+ cost) can be discounted There are only two downsides of this card:

• it's trait locked
• it depends on randomness (sometimes you draw ally almost immeditaley, sometimes you need to discard ten or something cards.

Rating (A-C) A- Almost any leadership ally-centric deck with Mystic trait should include this card
