This card/Spirit on the Field/Trash/Removed Zone can't be returned to the hand/deck by either player's effects.
Main - Accel: Cost 4 (Reduction: DK)(This effect can be used from your hand)
When you only control "Android" family Spirits/Ultimates, until the next (Opponent's End Step), you Life can't be reduced. After this effect resolves, put this card face-up on your Removed Zone.
[LV2][LV3] (When Attacks) Return an opposing Spirit and an opposing Ultimate to the bottom of the deck in any order.
Ruling: Even if all "Android" Spirits/Ultimates leave the field after the Accel effect activates, the effect continues activated.
