Testing
Pietra is lovely, beating face early and representing a bit of inevitability late. 10/10 Boros card, even though she makes a unique token.
Vorthos is a fun way to add a mission statement to your draft, and while it might not be a winning card is sure is a cool one.
Trigger happy does things, we all know this. Let's get to my last major testing/include.
Tchotchke Elemental is a weird one that I can't believe that more people haven't listed. It grows on tokens AND counters, making it, you guessed it, a Green aggro card! Note that it goes infinite* if you make a clone copy of it.
I think that this card is incredible and that more people would enjoy playing with it.
*while supplies last
May errata
It's probably
fine as-is, but I don't love the dice rolling as a standalone. I'll probably test it without the errata and see whether the potential upside/downside is tolerable. However, turning tokens into food is a cool ability. This card might be too good at stalling games, but it makes a lot of artifacts quickly and provides a very different axis for the counter deck to play on, so I think it's worth of testing.
Interested
Bag Check is a great if marginal upgrade to
Cancel, and all cubes should be full of dangerous cards. I'm just not sure if I'm into Cancel-with-upside.
Disallow is a personal favorite, as is
Mirrorshell Crab, but those two can do things that none of my other counterspells can do, whereas this is just more value on an old classic.
Omniclown is (kind of) a colorshifted
Realm-Cloaked Giant, just with an artifact twist, better keyword in trample, and (probably) useless Affinity for Robots. It might just be uncastable, though
Ignacio is very cool--everyone loves Treasures--but I haven't done the math. I wish the other members of this cycle were actually priced to move the way this one is. If they were, I'd probably test them
Hats?
I haven't done the math on how many hatted cards I have, but these two seem fun! Park Re-Entry seems like a slightly more juiced/less multicolored
Graceful Restoration, which is a card that's been on the outside of my cube looking in for a while. Haberthrasher is a monocolored but less consistent spin on
Corpse Knight, which has also been a BW card that I haven't responsibly had space for. (edit: why is the misprinted 2/3 Corpse Knight so cheap? That's an AWESOME cube card! Also, why is the normal version almost $2???)
Overall
This is a really cool set with more cards than I thought I might want! I, too, wish that WotC went further with the space theming, but I'll content myself with the beautiful basics and shocks. I'm glad that Un sets are alive and well, even if I'm not as sure I'll like the standalone draft experience as much as I liked Unstable.
