For example, if the current rule is draw 1, and the card “draw 2 and use ’em” is played, and the cards drawn are a Draw 4 (New Rule) and Let’s Simplify (Action). The player then plays the new rule card followed by the action to simplify, and removes the new rule; does the player draw the addition cards as per the new rule? We were not sure if having set aside one’s hand would mean that you couldn’t draw those extra cards until the “mini hand” was resolved.
A: You’d resolve the increased draw as soon as it was played, whether your hand is set aside or not. In other words, if you started with Draw 1, and, within the mini-hand played Draw 4, you’d draw 3 more cards, and put them in your set-aside main hand. Then you’d play the Let’s Simplify, and the Draw 4 card would go away.
Note that this ruling will also apply to Draw 3 Play 2 of Them (D3P2) and Fizzbin.
