Right, only played one. You made the restriction yourself! But I do like that solution quite a bit. I might as well put out my solution:
2 Processions, Watchtower, Workshop, Count. Pr-Pr-Workshop-Count. Gain Procession and workshop with the workshop, gain a duchy, two coppers, and +3 coins from the count. Then trash workshop for Procession, count for nothing, procession for count, topdeck the good cards with watchtower. Finally topdeck a watchtower with your 3 coins, repeat next turn. I don't remember where I got this idea from...
