Gave it a try, opened a laughably stupid pile of bombs, won the event. The set feels like a downgrade from Avatar: lots of ridiculous, must-answer bombs but several of the mechanics just don't seem to work. Still, WAY above spider-shit or turtles. Like let's look at the UW archetype: teamwork. Teamwork is a strong effect, but you can't really... build around it. One form of payoff works:
Captain America, who happens to just be an efficient creature that gives your team pseudo-vigilance. Then there's
Maria, who is... most of the time, just a Savannah Lions. As it almost-always is, UW is in reality a tempo flyers deck, where your best cards are gonna be
Falcon,
Justice, and
blue's 2/2 flyer workhorse of the set. I expect to see the 'teamwork matters' cards actually pay off maybe twice in this entire runtime.
RG is supposed to care about Power-Up, but don't be fooled: it's just RG stompy, again, as it has been in every single 10-archetype set of the last forever (though don't sleep on
Shang-Chi: this card is fucking sweet and is in part why I even opted to go to a prerelease. Pulling him felt great). UG is supposed to be +1/+1 counters, but it's really just a ramp deck that's gonna splash into a third color - because my god is the fixing ridiculous in this set. I could have easily played 5c sealed without any issues. WB is supposed to be pseudo-exalted with an equipment-lite theme, but in reality it's actually just dogshit and you're splashing for
The Kingpin,
Cloak and Dagger, or
Black Widow.
Everything that is not Grixis is just playing generic goodstuff, probably with a splash of 2 whole colors for individual bombs. Grixis, by contrast, is all about synergy: UR, UB, and RB all actually work with their themes and have the support necessary to pull off. The net result is that if you get the nuts, Grixis decks are gonna be unstoppable... but they suffer a lot more from someone drafting in your colors than do the other colors.
Also,
Squirrel Girl is a stupid card and the GGG costs are misleading. You'll have plenty of treasures - this is one of the best rares in the set and might just be the best. Some mythics may beat it.
