Full lists for the Commander 2018 decks are out.
They're not... bad, but they're not as exciting as the previous year's sets. These feel more like toolkits for building future decks more than fully realized decks on their own, honestly. Still want to get that Windgrace deck regardless
They're bad when you consider they raised the price and lowered the quality of reprints pretty substantially. That, and they all feel overall like collections of cheap bulk with low synergy. These decks used to be playable right out of the box and now it's just a weird jumbled mess.
That said I pre-ordered the whole set a long time ago and while I like the Esper and Bant decks enough too keep them (the commander ideas are great and I like the new cards in them), I have zero interest in the other two beyond one card from each of them (Tawnos in the Izzet deck and Xantcha in the Jund one).
I'm probably going to sell them and cut my losses.
Aminatou is probably the one I'm most excited for due to being able to maintain Stasis indefinitely and combos with a lot of different cards, especially Felidar Guardian and Altar of the Brood.
Yennett is also very exciting as a Zur alternative. Fun combo: Isochron Scepter + Mystical Tutor to set up the top card to Nexus of Fate. Attack with Yennett, it casts for free and gets shuffled into your deck. Infinite turns with a bulky flier with vigilance and menace. She's really cool.
Varina will be a great zombie tribal commander and she covers the 3 main colors of zombies for the first time and synergizes really well with them. I like.
Yuriko seems pretty cool if not only because she bypasses commander tax.
Estrid seems really interesting as a potential but less efficient alternative to blue Teferi. She has some pretty cool synergies with Chain Veil.
Kestia feels kind of like Tymna but with a bit more protection if you bestow her. Also just play Enchanted Evening and draw all the cards. A little disappointed she's not a God with indestructible though. I think bestow bypasses commander tax too though, so that's pretty neat.
Tuvasa is an enchantress commander for an enchantress deck. Not the most exciting design but still cool that that option exists.
