Forum:Royal Oppression vs Glads

Can I negate the special summon of a gladiator beast with royal oppression? and in that case, where i should use/chain the effect of the royal oppression? when they're going bakc to the deck or when they are special summoned by other gladiator beast?

Other question: When my opponent activates Macro Cosmos can I chain/use effect of Royal Oppression to destroy it? this is because Macro Cosmos Says: Special Summon Helios, or something like that, but what about if he doesn't activate That effect of Macro Cosmos, can I still activate the Oppression?.
