Forum:Crystal cards

When using a Crystal beast the card is destroyed and you put it in the spell/trap zone does the effect of the card still work but in the forum of a spell effect rather then a monster effect.

EX: Crystal Beast Emeralds effect is that you can choose one monster on your side of the field and switch it to defense mode. when it is destroyed the card then is placed in the spell/trap card zone. the same effect works or not?
