Thank God. I was really concerned since the last quest Paladin got was a meme called The Last Kaleidosaur. Paladin now has a great quest and probably has the best Reno style card as well with Sir Finley of the Sands.
I haven't wrapped my head around this one yet. The "value" stuff is obvious, but I'm not sure that this just doesn't want to be an aggro deck or midrange deck, especially considering that reborn and salhet's pride lend themselves more to that style of play.
This is possibly the second most powerful new quest revealed. I still think the Shaman one is the most so far. But it depends now entirely on how many Reborn minions we will get. Being able to copy a Reborn minion as a 2/2 is so much value. And since your deck needs a decent amount to make this quest worth it. It means after you complete the quest, you will have a very difficult board to deal with.
Even so, without using this on Reborn minions doesn't matter.
Immortal Prelate as a 2/2. Never fatigue again.
How about Mech Paladin and the ability to make a 2/2 copy of your insanely buffed Mech?
Turn 9, play A new Challenger and then get a 2/2 copy of that minion, which comes with Divine Shield and Taunt.
Tirion Fording sounds nice too on turn 10. Really annoying to deal with.
How about Undatakah as well. You should maintain the Deathrattle effects on the 2/2 version. Crazy!
