The brewlette buildaround for this week (until April 22nd) is Desperate Courier. Instead of using it with fast spells or ambush units, at least for the most part, I decided to use the synergy of cost reduction on the opponent's turn and Restrained Action. Courier is a 1-drop, so you can play it as your first Restrained Action unit and its cost reduction effect also applies to all the cards in your deck, so you can basically play a 3-drop when you would usually play a 2-drop as long as you have Courier on board. One "finishing" combo that you can do with that is to get Aurelian Merchant with Action the turn after you got Courier and to grab Development from the market. If you have something big on board, like a Riftfeeder Wasp, you can deal quite a bit of damage or at least force your opponent to go for some bad blocks.
Parul's Choice means you have more consistent access to Action and the other curses are there to make Choice more flexible (you can even use it to get more power by drawing Thicket Trap). The aegis effect of Choice can also come up, especially against control (where most of your curses are useless anyway). I also play some curse synergy units, but only as 1-of's because most of them aren't that great (Archgryffyn is strong, but Wasp usually does a better job, even on turn 5). I also play a lot of other units at 1 or 2 copies because they are situational and you can tutor them up with Action if their specific situation arises. Between 4 Archivist, Parul's Choice for Thicket Trap, some plunder and a lot of dual influence power the powerbase feels very consistent, although a bit slow at times. I tried to make up for that with a lot of early game, especially the cheap interaction like Permafrost or Desert Marshall.
As always with brewlette lists, craft with caution. This deck feels fine, but its far from the most efficient ladder grinder and it has some legendaries that are not great outside of specific decks (e.g. Restrained Action or Eloz).
