Notes & Combos
Regained is one of the most busted cards ever printed so the extended Bystial suite is warranted in my opinion. Bystials do come up in every non-SHS matchup, including Snake-Eye (toggle on when Flamberge attempts to crystalise I:P)
I cut Crossout because it's unironically not impactful enough to warrant a slot. Droll does practically the same thing against the format warping earth insect and is more versatile (it's a LOT more useful when going second for instance).
Zeus never came up (it's more for Unicorn bait against Kashtira) so I'd suggest cutting it for something like a second Dingirsu/I:P. You could also opt for 1 Jackalope 2 Tsuchinoko like one of my friends suggested (I just wanted the guaranteed level 3 body) if you want a lower chance of drawing multiples and having it hit itself.
Unfortunately, if you do play this list, you WILL lose games to bricking, as I ended up cutting cards like Scrap Recycler in favour of more extenders. Often times your suite of nonengine will be enough to stop their turn, but certain matchups (braindead being a big one) will feel like a lost cause.
