Funkfin Mech Paladin

Fill the board with mechs, around turns 5 to 6, throw out Bubblebot if you have about 3-4 mechs on board. With your mechs with divins shield, hopefully you may be able to end the game before around turns 8-9.
If Bubblebot it not drawn, fret not. Many mechs in the deck have divine shield, and with Funkfin, they can deal impressive damage early mid-game.
In the case you have a decent amount of mechs on board, but yet to draw Bubblebot or Funkfin, you should be able to rely on Crusader Aura for a board buff.
The Leviathan can be replaced with Mothership if the deck is too expensive.
Aim to get a Radar Detector in your starting hand, and play it as soon as possible. After that, if Muscle-O-Tron is hopefully drawn, you can get an early handbuff, with it either forged or unforged. If not, try to fill the board with cheap mechs. They should be pretty resistant to damage based board clears due to many of them having divine shield. If you are afraid that you may encounter many board clears, feel free to replace Noble Minibot with Tyr’s Tears, as that guarantees 3-4 2/2 when unforged or forged respectively.
This deck by itself may not be too powerful, but it does work against some other decks that are currently being used. Furthermore, without the Leviathan, the deck should be pretty cheap to make. Have fun with it.
