Forum:Royal Oppression and Divine Warning

how does Divine Warning and Royal Oppression differ in negating Special Summons? is it correct that DW cannot negate Macro Cosmos and Starlight Road but RO can? please im really confused about this, and can someone, (if ever) give examples of cards that RO can negate and DW can't? thanks alot June23ly 15:04, June 14, 2010 (UTC)
