Survive early game with Righteous Protector combined with many secrets (Mainly Redemption) and finish late game of with Sunkeeper Tarim. SecretKeeper is for early game rush, and also is a good way to stop tempo mage from bringing out their secrets. Divine Favour is for card draw after you play all your secrets, and Mind breaker is for against Warlock/Odd Paladin.
Basically, You want to control the early game using secrets and concentration, to always have a board.
Don’t play Redemption at the same time as Noble Sacrifice, unless you expect them to use spells or hero power to kill your minions (namely, The Annoyotrons from Giggling Inventor and Righteous Protector)
