For mine, I'd have to go with a turn that Kaia_Cougar played against me at Further Confusion with his Tanglebrook Lions deck. He had 3 [card]Lion's Den[/card]s, 3 [card]Kinship Studio[/card]s, 10 Home Havens, and 7 Lion Furres out, meaning that he was getting 22 AP every turn and he could reduce the cost of playing Havens by 21, more than enough to play any Haven ever printed for free. He started out by playing [card]The Flameroar Kings[/card], which returned all his Home Havens to his hand and allowed him to give a +1 bonus to all his Lions' PEs until end of turn for each Home Haven he played, and make all his Lions Greedy until end of turn whenever he played a non-Home Haven. Then he played all his Home Havens along with some other Haven (I don't remember which) for free, did some other stuff which left him with 6 AP, and swung at me with a bunch of Greedy Lions. I was so impressed with this setup that I had to actually write down exactly what he was swinging with:
2x [card]Raci the Temptress[/card]: 3 in all PEs + 10 from The Flameroar Kings + 7 from non-Home Havens = 20 pleasure each
[card]Pownsi[/card]: 7

[card]Haidar Sculptor[/card]: 5


Making for a total of 72, which was not only more than enough to take me down to 0 from the full 50

But what about the other 2 AP? Well, he wanted to be able to put out with some Furres on my turn in case I had something up my sleeve to stop the ones he was swinging with, which was a wise move. However, it turns out Seppel actually got a picture of the last move of this game, so we can see the highest possible amount of pleasure he could have done. If, instead of the Haidar Sculptor, he swung with these Furres:
[card]Pride Commander Osee[/card]: 8

2x [card]Loinblazer[/card]: 7

This would have made for a total of 109 Greedy pleasure, which is what I'm considering to be the record in spirit.
