Architect + engineer
This deck took me from around #25 god rank up to #4 with 10 wins and 1 loss.
A production & structures deck was one of the first decks I built when I started playing Faeria three months ago. It was fun, but I didn't win much with it at the time. Watching Amoeba play a similar deck on Zorni's Twitch channel after the Seifer Open #3 made me realize that the new Radiance "Steve" Scourge of Oversky makes it a LOT better. Having the sense to actually put in card draw this time around makes it better too. The main reason it's good is probably that it out-greeds control decks and the current meta is a control meta.
Here are some screenshots of a few of the wins: https://imgur.com/a/JnILGyi
To play it, mulligan for Faeria Tree and Gabrian Cistern. Build lands back defensively and then push forward on a side to put the Radiance near your opponent's face. Save your devouring plants to use on a Radiance turn or to protect Magda and Kaios.
