Deck Primer / Description

While the deck doesn't need to win via the following combo, there is an infinite nestled within (as there typically is with Paradox Engine decks).

1) Have Slobad, Iron Goblin, Scrap Trawler, and Paradox Engine on board. Have Skitterbeam Battalion castable and Metalwork Colossus in hand or graveyard.
2) Cast Colossus and sacrifice it to Slobad, netting 11 mana.
3) Cast Battalion, of whatever size you can cast - 2/2s will work.
4) Return Colossus to hand, sacrificing one real Battalion and one fake Battalion to do so.
5) When next you sacrifice Colossus to Slobad, return the Battalion to your hand.
6) Repeat.
7) You now have infinite Battalions with trample and haste.
