First attempt on release to create a fun Paladin deck with the new Quest.
The idea is to get through the early game with your Reborn minions and finish the Quest, after which you'll start copying the big bad Deathrattle minions. Magnetic is very strong here on both Mechano-Egg and Mechanical Whelp and their effects will be copied by the Hero Power.

It can escalate quite quickly from there on out, making 2/2 copies of a big Deathrattle minion every turn is very difficult for your opponent to deal with if they can't clear your entire board.

This is still an early attempt and it will be subject to (probably many) changes. Currently it may lack a little bit of draw. Dealing with a wide board may also be a problem. Wild Pyromancer may provide an answer there but I'm not sure what it should replace.

Feel free to experiment with the deck and let me know how it works out for you.
