Digisorption discounts a digivolution from your hand if you suspend one of your Digimon on the way in. You're converting a body's untapped status into memory, which is usually a great deal on the turn you go tall. Just remember the suspended Digimon is now attackable, so pick something you don't mind losing or something your opponent can't profitably hit.
16-10-1. <Digisorption> is a keyword effect. When a digivolution into a Digimon card with this effect in the hand would occur, by suspending 1 of your Digimon, the digivolution cost is reduced according to the value specified in the effect. This is shown on cards using text such as <Digisorption -3>. 16-10-2. <Digisorption> is an immediate-type effect that triggers when a digivolution into a card with this effect in the hand would occur. (For details, refer to 15-8-5 "Immediate-Type Effects") 16-10-3. "By suspending 1 of your Digimon" in <Digisorption> is an optional processing condition. If the content of that condition is executed, the processing for "the digivolution cost is reduced" will be mandatory.
