A: Well, first of all, so far, there is currently no single deck that contains both of these cards, however, you could easily end up with this happening if you combine your 5.0 and Remixx decks, since the former has Take Another Turn, and the latter has Taskmaster.
As mentioned in this FAQ, the results of Actions are enjoyed by the player receiving the card. However, the results of Take Another Turn don’t actually happen until the end of your current turn – but in the case of the Taskmaster having given it to you to play, yours isn’t the current turn, so you can’t take “Another” after it.
What you do is you have to wait until your next regular turn, and then you get to take your “Another” after that, so you take two turns in a row then.
