March of Machines Update

Making some larger scale changes in preparation for CubeCon 2023. Adding more support for a sacrifice theme. Of note, I have finally broken down and allowed adventure cards like Giant Killer and Foulmire Knight.

Elvish Lyrist: Taking a naturalize source away from white and giving it to strictly green.
Giant Killer: Cutting out a city's blessing card for a different defensive creature.
Clockwork Drawbridge: Another tapper effect for white. Hotshot mechanic just felt so anemic and I really don't want to make people think there are vehicles in here.
Akki Scrapchomper: This is the only cards from MoM I'm trying out immediately and I'm very excited for it. I'm always excited for new goblins, but this one says sacrifice and draw a card.
Tajuru Blightblade: Leaning into tribal matters more with this swap.
Sunblade Elf: Selesnya really doesn't need more help but everytime I see that this card isn't in here I feel the urge to put it back in.
Universal Automaton: Leaning more into tribal matter again.
Bag of Devouring: Sac outlet and a pseudo-payoff for sacrifice. Reaper's Talisman is really good and I will miss it, but we need to curb life gain effects.
Ashnod, Flesh Mechanist: Not sure why I didn't add this with Brother's War. Adds to token complexity, but it seems quite strong.
Changeling Outcast: Leaning more into Tribal matters with this one.
Foulmire Knight: Leaning more into Tribal Matter with this one.
Raven's Crime: Recursive discard to work with Groundskeeper.
Ground Rift: Another storm card to eat with Nivmagus Elemental as well as adding another Falter effect to enable alpha strikes.
Thoughtpicker Witch: Leaning more into Sac strategies with this one. I am cutting Gutterbones here just in case the recursive black creatures become too much. He may come back.
Darkblast: I've been wanting to add this for some time and Sticher's Supplier doesn't really synergize with anything as of yet. I wish there were good pay-offs for self mill at 1-mana.
Mortician Beetle: Leaning more into Sacrifice strategies with this one. Diregraf Ghoul is one of the few vanilla creatures left and was only in here because of the relevant type line.
Memory Sluice: Cutting the worst cantrip I have for another mill spell.
Mutagenic Growth: Cutting a vanilla elf for a dynamic pump spell.

Final Thoughts

March of the Machines had very few 1-drops I was intrigued by, but it did give me the opportunity to lean further into some strategies I want to promote more.
The Captive Weird and Tarkir Duneshaper interest me, but I don't like adding too many flip cards.

Here's hoping this cube gets picked to be featured at CubeCon 2023.
