Want to play one last hurrah to standard Secret and Dragon decks? Here you get best of both worlds! 
One beloved/hated decks back in pre-WOG was secret paladin, and while the concept isn't as strong due to the lack of many early drops as it used to had, Templar brings the dragon synergy to the archetype, and coupled with some early game divine shield shananigans you can have some great action all game long.

The strategy is to play good old curvestone, though we somewhat lack a decent 2 drop, your turn 2 can be used to solidify whatever you got from turn 1, with secrets or more one drops. If on coin, you can probably play Muster for Dragons (Nightbane Templar) and fill up your board. 

Be aware of when you can combo Rallying Blade, you should always keep it vs zoo or shaman, and vs anything if you also have Selfless Hero or Argent Squire in hand.

If you have a dragon such as Faerie Dragon and Nightbane, keep it all. Higher value mana dragons are also a keep if you have Nightbane in hand. 

Try to mulligan all of your secrets, unless it's Noble Sac vs aggro, or Redemption vs Warrior. It's just amazing to see Selfless Hero/Squire come back after two swing sof Fiery Win Axe.  But otherwise, mulligan aways. You want to draw your secrets with Dr. 6 (aka Mysterious Challenger, for newcomers).

Tirion and Onyxia are your game finishers. If for some reason you didn't trigger Competitive Spirit yet, wait till you see it happens.
