The general gameplan of the deck is pretty straight forward - flood the board with units as fast as possible, then either overwhelm them with the pressure or use Argo to stun the enemy board and swing in with everything. There is some added complexity with the amplify cards and exhaust effects, which impose constant decision points between value and tempo.
Bastion Garrison simplifies this problem by giving every amplify guaranteed value, and I was always happy to see a copy in the mulligan. I had a 60% win rate the last 20 games to masters which felt roughly typical for the deck, and I know it could have been even higher if I played better and fully optimized the deck.
Daring Swordmaster
This card is certainly the strangest 4-of in the list, but it actually felt pretty good for me. Let me be clear: I almost never play the 4 cost 1/1, as it is in the deck for the free draw and as a good plunder/market target. Since this deck almost always has a soldier on the field, the fate text has a high chance of going off. Whether or not this means the card is worth running is still something I am trying to figure out.
Notable Exclusions
Many exclusions of the deck (including the most notable,
Speed Grafter) were cut because I'm just too stubborn to craft them. I definitely would try out speed grafter if I had it, probably replacing the etchings and cutting
Daring Swordmaster or
Relay Point for any extra power. Other cards I wanted to try include a fourth copy of
Martial Efficiency and a third copy of
Argo Ironthorn. Some other cards that were cut include
Shock Troops (too fragile),
Asri Scout (weak body/awkward effect), and
Mask Maker. Mask maker could have potential and I haven't tested him much, but I worry he doesn't do enough for the overall game plan.
Market
I liked where the market ended up, but if speed grafter was put in, I would try
The Speaking Circle in place of Ubsat and
Celebration instead of
Cast Out. The rest is pretty self-explanatory; Whisper is permafrost protection, Edict is good for a counterspell and Hysteria is good for slow unit decks like Mandrakes.
The summon is a soldier and it combos in so nicely.
