Probably the least popular first pick Discipline, but I’ve found in the context of solo/2p, to be the best choice to build your starter deck around. The reasons are laid out below.

Firstly, in solo/2p, versatility is greater valued as a deckbuilding goal, and I argue should even be slightly biased towards clue discovery, no matter your chosen character. 3 Intellect is the reasonable spot where you can start investigating right off the bat (assuming Standard, Hard/Expert solo/2p needs different deckbuilding considerations), especially in earlier campaign scenarios where the shroud values at or around your starting location tend to be 2-3.

Compared against a +Willpower Lily build who needs to hard mull or draw/Arcane Initiate into either of her 2x Sixth Sense, a +Intellect Lily can more reliably start pulling clues early, especially with some support from a good range of cards such as Flashlights or pitched icons.

Secondly, this Discipline’s draw power has the highest potential in terms of game impact. In solo/2p, you can’t rely on other investigators to cover for you while you draw into your dream min-maxed combo. Quite often you got to deal with whatever the obstacle is yourself, which can range from show-stopping Arkham nonsense such as a Locked Door, to a stubborn enemy that just spawned on you while you aren’t “ready”.

The +WIP Discipline healing ability is a nice to have ability, but its scope to bail you out of a bad situation is extremely narrow. The +AGI combo ability is cool to pull off, but honestly if you already have the setup to have a reasonable shot at 3 different Fight/Evades, it’s more of an icing-on-the-cake-cool-to-have but not absolutely game saving ability, and is only limited to getting you out of bad situations involving enemies. The +STR Discipline’s AOOless +5 is pretty flexible, but I would argue the ability to draw into potential high-impact out options such as a Promise of Power or Spectral Razor in an emergency, has better value in solo/2p. Even better, this Discipline’s ability gets stronger the more desperately you need it, when you have lesser cards/options in hand, and just need something to quickly stabilise yourself.

Lastly, you probably won’t use the ability more than a couple of times each scenario, but if you do, it’s when you are desperate. Don’t be greedy and wait for when you have no or 1 card in hand, pulling for 3 cards or more in 1 action is already pretty good especially in a Guardian/Mystic.

All in all, do consider this as your first Discipline the next time you build for solo/2p Lily, and try a deck that is built around the ability to replenish cards the quicker you use them. Skill cards, fast abilities, cards with a versatile spread of icons, gain value in such a deck approach. Which, I would argue, dovetails nicely into the deckbuilding considerations for lower player counts.

(Review edited to remove a mistaken non-critical point I made about the Discipline potentially unbreaking itself the same turn you break it)

Flipping this back is trickier than it sounds. It is a 2 turns process, because before the round ends, you must always draw 1 card. Unless you get a weakness, "after the round ends" will already had passed a process of drawing 1 card.

The only kind of round you can flip back is that you must first start the round at 1 card, use it up somehow in treachery test or inside your turn, then draw a new one to 1 card right before the end of round. (= Did not have 2 or more cards at any point.)

• First you must find a turn where you can dump an entire hand of X cards (X > 1) to 0. Before this round ends, you will draw one card. If not getting a weakness, making this round's hand count : 1 min X max, therefore you cannot flip back in this "dump turn".
• The next turn, you begin with 1 card you just draw. You must also find a way to dump this card away, making your hand 0 once again. Before this round ends, you will draw one card. Making this round 0 min 1 max, then you can flip it because both are less than 2.
  • Supposed that you failed to use this 1 card on this turn (no eligible test to commit, the cost is high, Fast criteria not quite right, etc.) the end round draw will make your hand 1 + 1 = 2 cards. When this happen, you must start the process all over again, trying to zero out the hand on the next turn, then try again to zero out the 1 new card on the next next turn.

In other words, "if your hand did not have 2 or more cards" can be interpreted as : "You must make your hand 0 card at the end of turn, for 2 consecutive rounds."

Something that I haven't seen mentioned yet in any discussions about this card is its cheeky interaction with her signature Weakness (which she may have up to four copies of). Drawing cards and flipping the asset are two discreet sentences and in that order. Thus, if you draw Burden of Destiny, this Discipline will still be Unbroken and a legal target for the weakness. Since it was about to flip anyways - you lose nothing further by choosing it!

The 'cannot flip back this round' clause on Burden of Destiny does mean that the second step doesn't immediately reset the asset to Unbroken, which prevents this from reaching cheese levels, but it otherwise isn't a concern as the discipline wasn't going to flip back at the end of the round anyways (on account of drawing up to 5 cards).
