I've been really enjoying this set, it seems a bit slower and more complex to me than the last couple. All the colors except green seem decent and even the aggro decks need a lot of synergy to function well.
I went 7-1 with this Dimir Descend deck on the back of [[Aclazotz]] and two Uchies. The playset of [[Echo of Dusk]] was really good - turns out a 2 mana 3/3 lifelink is pretty dece.
I'm super bad at picking artifacts. But the payoff of artifact synergy is crazy good from what I've seen
