According to the rulebook
After drawing all cards at the end of your turn, if you have more cards in hand than the maximum, you must choose and discard cards from your hand until you no longer have too many.
This means that if I play A Game of Dice during my Action Phase, I will draw my normal card during my Dynasty Phase, then another 2 from AGoD before my turn ends, and then I will discard to my current maximum (if needed).
What happens with effects like In Stillness, Forge the Soul targeting a Kensai and not Equiping a weapon? The card reads: "...you may put this Strategy back in your hand before the turn ends".
Does this mean I can trump the maximum hand size and end my turn with 9 cards?
For Legacy fans, does Prayers & Blessings works the same way?

"Before the turn ends" means immediately before the turn ends. This will be after you discard down to maximum hand size, so In Stillness, Forge the Soul would allow you to carry an extra card into the next turn.

Per the new Reference Rules document, effects that happen "before the end of the turn" occur prior to the normal end of turn draw and discard. Therefore, this ruling is *REVERSED*. In Stillness, Forge the Soul will not allow you to exceed the maximum hand size.
