Forum:Celestia vs bottomless trap hole

Hypothetically, lets say i have 3 cards set: Waboku, Bottomless Trap Hole, and Ojama Trio. If my opponent activates summons Celestia and uses the effect to destroy my Bottomless Trap Hole, could i chain it? i was wondering the same concept with mobius. Does my opponent have to call priority before i could activate anything? or i do i have to tell him/her that i'm activating bottomless trap hole and they destroy the other 2 cards Ittxwil147 05:10, February 3, 2010 (UTC)
