Thank you for your responses!
As a follow up to #3 above, we happened to be playing the scenario "Under the Broken City" which states "At the end of your turn, recharge a random card from your discard pile". So, given out example, if you recharge this random card from your discard pile BEFORE you reset your hand, you would still be alive. If AFTER, you would die. So, the question is, since both resetting your hand and this recharge happen "at the end of your turn", which one happens first?
Or, in a more general sense, if you have 2 effects that take place "at the end of your turn", does the player decide in which order they happen?
