Kind of nitpicking here, and I'm pretty sure I already know the rule, but...
Storyteller says to "Play up to 3 Treasures...". So say I play a Venture with Storyteller, then the Venture tells me to play a 4th Treasure. 4 is not up to 3. Should I be able to play the 4th Treasure? Or only up to 3? Same would go for Counterfeit I guess.
Similar thing with Throne Room / Royal Carriage. Say I play TR on a Smithy, play the Smithy twice, then call RC to play the Smithy a 3rd time. But the TR said to play the Smithy twice -- no more, no less (note that I could not have played the Smithy just once if I wanted to). Also, note that playing RC on the TR, not the Smithy, wouldn't contradict any text.
I'm like 99.9% sure that either of these scenarios are totally fine. But they seem to contradict the text on Storyteller & TR, just sayin.
