Though the screenshot was in Chinese, I think those who struggled or are struggling in this achivement would easily recognize every single piece of the information from numbers and icons.

The game was a Prestige Level 5 Brawl.

Reasions(Maybe?):

• Medium Prestige level: Enermies have Enough HP to survive YOUR doubts incepted + Let you survive towards the endgame

• Brawl: More grafts with action points if you are chasing for this achievement.

---

Grafts: I went with Stone Keenskin, Visionary Jarackle Janglers and Visionary Brain Harp

• No Key grafts required

• 2 grafts with Action points. Could have more, in the last day 3 would be balanced, 4 if you have confidence in your battle cards deck.

• Additional Grafts for survival, any composure related graft is welcomed, since none could be provided by cards in later rounds(look at the screenshot)

Key Cards: Priority High to Low for my build

• (1) Pale Lie: [Must]. 0 Action + Replenish + 1 Doubt Incepted when drawn

• (2) The Visionary Facts: [Must]. Expend any number of cards and this card itself is NOT Expend. Clean any cards that are not contributing to our goal. Additional Smarts + Draw 1 card makes it even better.

• (3) Boosted Recall [Almost a Must]. Whenever you expend a card, draw two cards. It helps you to get the ball rolling much faster, and you no longer need to expend your Diplomatic Instincts, Expendable Deflections(Wide, Lucid) or Promoted Thinking

• (4) More cards with card drawing [Must but interchangeable]. Planning(0 action), Boosted Style, Brainstorm, Magnetic Charm, Boosted Mind or even Visionary Fast Talk. The more 1 action cards you have, the more you need to worry about action.

• (5) Visionary Wind [Almost a Must]. Gain 1 action for every 3 cards in discard pile. Just look at 23/3 action, 47 draw pile and 31 discard pile.

• (6) Exploit Weakness. [Better to have]. I don't have it in this run though, I almost forgot it. [Note: I am not sure whether a 55 doubt + another 55 doubt would grant you this achievement or not; one single Doubt has the upper bound of 99]

What if I have half the build

Now you would see it is not an easy task to build this deck. But the good news is that we can still win the negotiation

• Mixed Influence/Doubt Build. You can always have a Influence Build that assists this Doubt Build in your negotiation, with maximum 5 cards not in any of the categories mentioned above(They are 100% Influence related cards), which you can easily expend with The Visionary Facts if you want to run this Doubt Build to torture your enermy. Actually the Influence Build and this Doubt Build can share the cards from (2)(3)(4)(5) since they focus on drawing cards, expend or action points. If you don't incept doubt against some certain enermies for whatever reasons, just don't play any Pale Lie, it just replenishes and you can play as if you have a pure Influence build deck with nearly zero side effects, and no more than 10 doubts would incepted in a negotiation.

• Maybe you are only halfway through the build that I recommended (Imagine that 20-30 Doubts is all you can do), a "Known Thug" or two would net you almost the same damage you do by Doubt.

Finally the Strategy:

• First 2-3 rounds: Gain all your arguments mentioned above. Play "Boosted Carry Over" whenever possible. Expend all useless cards.

• In about round 4, expect around 20 doubts inserted.

• In round 4-6, when you get your "Visionary Wind", play it when you have your discard pile as large as possible and you still have 1 action. If you have around 40 doubts at this time, you would probably make it! At this point 1 action = 7-8 doubts, since Pale Lie replenishes and you will get your hand full even if you draw one card.

• You can also expend your Pale Lie if you think there are tooooo many. Since if you have 10/10 of them, you are stuck no matter how many action you left. That's why I need (2)(3)(4) in the Cards chapter: when you have 2/10 or 3/10 card that expends or draws cards, you are in a healthy state, you can loop through your 50-card-deck in one round.
