Replicator Engine go brrrrrr

This deck is kind of like a clockroach deck, but somehow both worse and more fun.

The basic idea is to get a bunch of Replicator Engines in your deck to 0 or 1 cost (battle skills and stat boosts are a bonus, but not required) and play as many of them as possible, then watch them die, shuffle your void into your deck and do it again. And again. And again!

The best way to do this is to use Messenger Hawk to put four copies of an already-buffed Replicator Engine since you can immediately bring them out by playing the one in your hand. Those two cards are your primary targets for Know When to Hold 'em but if you've already got them, then either Lumen Reclaimer or Grodov's Stranger would be your next best option.

As a last note, it's worth keeping track of how many Replicator Engines are in your deck at any given time so that you don't accidentally play one without any to draw. Regardless, there's enough draw in the deck to ensure that it's not the end of the world if that happens anyway.

Have fun!
