10/1/2009: When figuring a creature's power and toughness, apply effects in a series of sublayers in the following order: (a) effects from characteristic-defining abilities; (b) effects that set power and/or toughness to a specific number or value; (c) effects that modify power and/or toughness but don't set power and/or toughness to a specific number or value; (d) changes from counters; (e) effects that switch a creature's power and toughness. This means that effects that switch power and toughness are always applied last when determining a creature's power and toughness, even if other power/toughness-changing effects are created later in the turn.
