Sorry to bump an old thread, but here is a new easy mode solution for 12 VP tokens per turn:
Hand is KC, KC, Jack-of-all-Trades, Mine, Bishop.
KC-KC, then Jack. Don't trash anything with Jack. This results in 3x Silver, Mine, Bishop in hand.
Now Mine to convert all the Silvers to Golds. Then trash them all with Bishop for 12 VP tokens.
Another one that only gets 10 VP tokens per turn in easy mode but can maybe be tweaked to do better:
Hand is KC, KC, Trusty Steed, Bishop, Bishop.
KC-KC, then Trusty Steed for: +$2, gain 4 Silvers; +2 cards, +$2; +2 cards, +$2. Now you have $6 and your hand contains two Bishops and four Silvers. KC one Bishop, trashing 3 Silvers for 6 VP tokens. KC the other Bishop, trashing one Silver and two of nothing for 4 VP tokens. In total, 10 VP tokens.
Would be nice if something could be done with the $12 you have to spend after doing this.
Another one for 12 VP tokens per turn in easy mode:
Hand is KC, KC, Bag of Gold, Smithy, Bishop.
KC-KC, then Bag of Gold, then Smithy to draw the 3x Golds, then Bishop to trash them.
