Probably the most powerful faction right now. I've originally started with Aaaaaaaaa's
Xenan Midrange, but ended up replacing many cards. I like what I ended up with, since this deck has a high win rate against Project, Aggro and Hunt decks which make up the majority of the meta.
Most of the time, you want to play defensively by using your excellent removal to stall the game while gaining life from
Hive Queen Uther and drawing cards with Nightfall,
Insatiable Anteater and
The Big Wheel.
Teacher of Humility will make the opponent's Nightfall draws (or any other extra draws) much worse, and you can get her through with
Minotaur Lighthoof who also doubles as relic removal versus those pesky
The Creation Project decks.
Feed the Hecaton can swing the game around by removing your opponent's big threats, and the deck has plenty of units that activate it.
Shrivel outright kills aggressive units and many midrange annoyances like
Hive Queen Uther and
Ziat, Steelwarren Reeve. For bigger threats like the
Alluring Predator, it can be used as a combat trick in combination with one of your units.
Insatiable Anteater draws you a card every turn in which the opponent draws an extra card by any means, not just through Nightfall (even if they
Seek Power).
Swift Subverter can castrate your opponent's
Hive Queen Uther or any other card with a Summon effect for that matter (which includes most Hunt cards and
The Winter Fox).
And of course,
Ziat, Steelwarren Reeve is an
Exploit on a big stick that you can reuse with the market
Recovery.
Also, you shouldn't keep 2 power hands to begin with. Don't keep a hand just assuming that you will draw power in time - it is likely that you won't.
