[Blocker]
[When Digivolving] 1 of your other Digimon may digivolve into a level 6 or lower Digimon card with [Greymon] in its name in your hand for the digivolution cost. When that Digimon would digivolve by this effect, reduce the digivolution cost by 2.

[Blocker] (When an opponent's Digimon attacks, you may suspend this Digimon to force the opponent to attack it instead.)
