Thermal Flux (CSP 49, foil) is a blue instant from the Coldsnap set that can add or remove the snow supertype from a target permanent. It offers a modal choice to either make a nonsnow permanent into snow or to strip snow from a snow permanent until end of turn and also schedules drawing a card at the beginning of the next turn's upkeep. This card functions as a one-mana interaction useful both for enabling or disabling snow-based synergies and for card advantage on the following upkeep.
