Generally you want to draw your cards which draw more cards so you're looking for:
Hydrologist - just one as you want curator to draw one later.
Stonehill Defender - Great to grab a flex card or another Tirion.
Truesilver Champion - This card is rarely denied value.
Elise the Trailblazer - If you can get this card off early you'll enjoy the value earlier of course.
You need to control the board early-game to survive to your healing cards late-game.
Stonehill Defender - This card is also a must against aggro as you'll need the taunt to protect your health and to generate more taunts.
Truesilver Champion - You'll need this against most aggro decks to heal and clear.
Doomsayer - This card is also excellent early against aggro.
The deck holds up just fine against most mid range decks if you manage your removal.
Make sure to generate value from your value cards but don't draw from your deck unless it's absolutely necessary. This deck can easily take control decks to fatigue so you don't want to overdraw.
Note: Against Taunt Warrior you need to tempo out and pressure them before they can generate value from the quest. However, be careful not to overextend into brawl.
Try and play Elise the Trailblazer as early as possible for value.
A control/fatigue style Paladin deck which goes for maximum value into late game. I don’t enjoy playing aggro and so designing a control deck that can compete in an aggro meta is a challenge but one that I think that this deck can pull off.
Against aggro, board clears and early taunts control into late game heals. Against control, value into late game can be overwhelming to an opponent as you play large taunts over and over again.
Elise the Trailblazer can be replaced with anything but late game against Priest/Control Paladin may suffer as a result. If the meta is primarily aggro then replacing this card with more defense (such as a Tar Creeper) is recommended.
