Creature - Merfolk Wizard 1/2, 2U (3) {T}: Switch target creature's power and toughness until end of turn. "Blasted fishtails! It's not enough that they meddle with my head, but they twist my body as well." —Tahngarth of the Weatherlight
Illus. Steve Prescott
11/1/2005: Note that the wording "Effects that alter the creature's power alter its toughness instead, and vice versa, this turn" has been removed.
2/1/2007: This is the timeshifted version of Dwarven Thaumaturgist.
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.
