How about this:

Protector of Mortality
Creature - Human Knight
First strike
Creatures you control can't leave the battlefield unless they die.
"Till death do us part."
2/2

Protects your creatures from StP, Terminus, Karakas and bounce, among other things. Also combines neatly with RiP or Samurai of the Pale Curtain for an invincible army.

When Guardian of the Conclave enters the battlefield, choose one:
* You gain hexproof until end of turn.
* Until end of turn, spells and abilities your opponents control can't cause you to sacrifice permanents.
2/2
That's a pretty nifty design.
