Patron+Pursue: buy Pursue, reveal 4 Patrons for +4 Coffers, spend 2 Coffers. Repeat.
I missed this one for the item of only buying events without gaining and playing cards. With the new Coffers ruling, Patron seems to be pretty useful for loops. Here are some more Patron examples with Fated:
Buy Scouting Party, shuffle 3 Fated Patrons revealing them for +3 Coffers, draw and discard them, spend 2 Coffers. Repeat.
Buy Gamble, shuffle 1 Fated Patron revealing it for +1 Coffer, revealing it with Gamble for +1 Coffer, spend 2 Coffers. Repeat. [Probably useless time waster]
I guess, using the Fated trait moves the card and so Avoid cannot move it as it is not among the to-be-shuffled cards where expected, right? Otherwise, every Avoid bought would yield +$1 on the next shuffle by discarding 3 uselessly revealed Fated Patrons which could make the Gamble loop above productive.
In the Fortress case, it seems, that Priest is the only way to produce any useful economy on trashing cards. So without ever gaining or playing or using Patron, we need Priest in the Fortress loop as well as Traveling Fair to produce the +buy we need. For the trashing events we can choose among Advance, Enhance, Maelstrom, Peril and Trade.
I will update the previous post accordingly.
