Question re Celebi EX's Time Recall Ability

[TuxedoBlack]

Assume I have an active Hydreigon (ND) that evolved from a Zweilous (DrX). The Hydreigon is a D type Pokémon and the Zweilous is a Dragon type Pokémon. If I also have a Celebi EX on my bench and wish to use its Time Recall Ability to attack with Zweilous, does the attack originate from the Dark (Hydreigon) or Dragon (Zweilous) type Poké should I wish to inflict 2X damage onto the defending Poké? Thanks.

Hydreugon is the Pokemon that is attacking. It will count as a Dark type attack for W&R purposes.
