In the following I abbreviate Team Galactic's Wager from the mysterious treasures expansion to "TGW". For a card such as TGW where both players must shuffle their hand into their deck and draw, what are the minimum requirements for hand and deck size. Can TGW be played even if it is the only card in your hand, your opponent has no hand and neither play has a deck under the guise that the game does not know the effect from the card yet? I have noticed you cannot use energy draw on an empty deck as the card must have some effect and cost is not an effect. What is cost and what is effect in terms of TGW? Ie. if you have no deck is the potential of losing some of your cards (ie shuffling 17 to draw 3) to allow an attack that searches the deck to function or to stop decking? What about if it is the only card in your hand, can you play it with the effect of disrupting your opponent's hand?
