[OP05-115_p3] - Two-Hundred Million Volts Amaru

I dealt damage to my opponent when they had 2 Life cards, and my opponent activated the [Trigger] effect of "OP05-115 Two-Hundred Million Volts Amaru", adding 1 card from the top of their deck to the top of their Life cards. In this case, can I use this [Your Turn] effect to trash 1 card from the top of each of my and my opponent's Life cards?

Yes, you can.
