Transmutation⁣ - Chronicles⁣ (Common)

Transmutation allows you to switch a target creature's power and toughness until the end of turn, which can be used to weaken an opponent's creature or bolster your own for a surprise attack. This instant can create advantageous combat situations or protect your life total by reducing damage from blockers. It's particularly effective in decks that utilise combat tricks or need to manipulate stats for tactical benefits.
