Forum:DED's revival effect

I have 2 questions about Destiny End Dragoon's effect 1:can i do it multiple times in the same standby phase? for example the guy plays royal oppression pays the cost to negate the summoning of DED then i remove another D-Hero to summon him again and i keep doing it until i am out of heroes or he is out of life points?the other:removing a d-hero targets a D-Hero? for example: can i summon him back if necrovalley is in the field? --JJXY (talk • contribs) 18:57, August 16, 2010 (UTC)
