Abzan Sneak Attack Aggro Abzan value creatures early. Rhino and Anafenza in the mid game. Plenty of removal.
Seeker and Rhino combined with
Become Immense can put the game away quickly with
Seeker's life gain and Rhino's trample. Even if they have blockers Rhinos are going to hit for a ton regardless and
seeker will gain 9 life and take out a blocker if there is one.
