So, I had an interesting turn in a recent game. The kingdom was a mixture of Nocturne and Prosperity, including Platinums. There were no village-type cards or lab-type cards, the only multi-card draws were Rabble and Tragic Hero. Heirlooms were Magic Lamp and Haunted Mirror, both of which by this point I'd already trashed for the three Wishes and the Ghost
I had a turn where I played Ghost, which hit Peddler. So, my next turn I started with 7 cards and 3 actions. As it turned out, I had two wishes in my hand (I think, or at least one at the start, I might've drawn the second one during the turn). I played a wish, gained a Tragic Hero, and immediately played it. This left me with 9 cards in my hand, causing the Tragic Hero to be trashed, for a Platinum. Then I used Necromancer to play the newly-trashed Tragic Hero for yet another Platinum, then finally I played my second wish to get a Tragic Hero, play it, and get a Platinum. So, in effect, I was able to turn 2 Wishes indirectly into Platina! And to get THREE Platina in a single turn! And then, I was able to buy a Colony too in that turn's buy phase
Seems a bit mean to gain a Tragic Hero only to immediately sacrifice him, but, well, I guess that's what makes him so Tragic
