Question

If a Digimon affected by this card's [On Play] [When Digivolving] effect later gains a digivolution card, can it now attack or block?

Answer

No, it can't.

This effect affects 1 of your opponent's Digimon with no digivolution cards, and the processing prevents that Digimon from attacking or blocking until their turn ends.

Even if it gains a digivolution card after being affected by the effect, the effect will continue processing.
