Taking Colossus infinite! Minor adjustments to the Metalwork Colossus shell I've been playing for the past few months, with the inclusion of
Paradoxical Outcome
and Aetherflux Reservoir for an added win-con.
Scrap Trawler
gives us the ability to go infinite.
In reality the infinite combo won't happen often and really isn't necessary. What
Scrap Trawler
does in combination with Metalwork Colossus is allow us to play and draw quite a few cards on any given turn without the need to cast a sorcery. This can be used purely as a draw engine or as a win-con if Aetherflux Reservoir is on the battlefield.
How to go infinite: have two
Scrap Trawler
s, two artifact cost reducers, and enough artifacts in play to make Metalwork Colossus free to play, along with a Colossus in the graveyard and one in hand or on the battlefield. From here you can infinitely sacrifice two artifacts (one being a Colossus) to return a Colossus from graveyard to hand, play it, and repeat. The second artifact should be one of the 2-cost draw-card artifacts, allowing you to draw as many cards as you want. Of course, each time you do this Aetherflux ticks up a notch.
How feasible is the combo? In my experience playing standard Colossus and Paradoxical Colossus it is common to have a stalemate on the board once the first Colossus hits. Furthermore, Saheeli Rai makes it easier to generate a second Trawler as soon as you play the first, making it much more likely. Also, given that all the pieces of this puzzle could be in play as early as turn 5 it gives a potential infinite as early as that. But really, this is just one more win-con in a deck full of options. The best part is no cards were added for this combo that aren't already great in this deck on their own merit. Against Control matchups it wouldn't be impossible to hold nearly all the pieces to this in hand for a turn they are tapped out and unload for the win (start with a Herald, then Inspector, Trawlers then cost 1 each and Colossus should be free).
Let me know what you think, or if I missed something in my calculations, and feel free to upvote if you think this could work! Thanks!
