One ruling from Wizards of the Coast
- 1 October 2009If multiple effects modify a player's hand size, apply them in timestamp order. For example, if you put Cursed Rack (an artifact that sets a chosen player's maximum hand size to four) onto the battlefield choosing your opponent and then put Gnat Miser onto the battlefield, your opponent will have a maximum hand size of three. However, if those permanents entered in the opposite order, your opponent's maximum hand size would be four.
