Cardsphere Picks: March of the Machine

As the Phyrexian machine marches toward total assimilation of the Magic multiverse, it is up to the Cardsphere staff and community members to hold fast, fight the good fight, and make some picks for their favorite cards in the upcoming April set release.
This time around, Discord moderator tunnel snake Bodey is joined by a trio of probably-not-Phyrexian-sleeper-agents from the Discord community, followmylogic, Dunkleskog, and wetlettuce. As always these picks can be based on any criteria, such as power level, artwork, flavor, etc. No criteria is off limits. Without further adieu, let's see what kind of compleated cardboard we're excited to become infected with.
Bodey

Surge of Salvation
This is what Veil of Summer probably should have been. I'm not sure if it makes the cut in white Commander decks that also have access to blue or green but I wouldn't fault anyone for playing it and will probably try to squeeze it in somewhere myself. Being able to blank a damage-based sweeper like Blasphemous Act

followmylogic

Invasion of Ravnica
This #1 card in the set is our first battle. Only time will tell if flipping these will be worth it, but a five mana Meteor Golem
Chrome Host Seedshark
New shark just dropped. Galazeth Prismari
Thalia and The Gitrog Monster
Between this and Drana and LinvalaJunk Abzan player inside me is quaking. First strike AND deathtouch; it ramps, it draws cards; stax but not brutal. It may not be the most powerful four drop in existence, but I can't wait to unclog this frog.
Dunkleskog

Invasion of Ikoria
What does tacking one more green pip onto Green Sun’s Zenith
Rona, Herald of Invasion
This is a very interesting card to play as a commander. Repeatable looting is always good, and you can do it even faster with some cheap legendary spells. But the backside is what’s really interesting to me here – you can ping your own Rona, Tolarian Obliterator. That gives me a great excuse to play Prodigal Sorcerer
Preening Champion
Taking a step away from Commander for a moment, let’s look at this peacock. In the context of March of the Machine Limited, this nets you two bodies on board, one of which is a 2/2 flier, and it has the creature type Knight. This slots very nicely into both the UR Convoke archetype and the UW Knights archetype at a solid rate. I’ll definitely be picking it highly when I start drafting March of the Machine.

Khenra Spellspear // Gitaxian Spellstalker
This card looks fantastic. One of the few Phyrexian transform creatures that I would happily transform on curve. Transforming on Turn 3 feels much safer as opponents are less likely to have removal in lieu of building their board. And the back side? Just full of awesome keywords. Double prowess (hah!) means it can grow large very quickly, trample to push through the extra power it gains, and ward 2 for some soft protection while you're piling on more power. And awesome creepy metal art to boot. Is this good enough for Constructed, I have no clue. But I just love everything about this card, and hope to play as many copies as I can in Limited.
Seal from Existence
Wait, is that a protection ability on a removal spell? Amazing. Anything to help mitigate the drawback of an otherwise powerful removal spell. Ward 3 seems like the perfect balanced amount as Disenchant
Etali, Primal Conqueror // Etali, Primal Sickness
I often find myself overwhelmed with choices when trying to build an EDH deck. Eventually, I decided "Hey, why not just play my opponents' things instead?", and that made all the difference. The first iteration of Etali, Primal Storm
