* Since you are only activating the Normal Spell Card’s effect, and not the Normal Spell Card itself, you do not pay costs and you do not have to meet any activation requirements. For example, you would not pay 1000 Life Points for “Confiscation”, or discard 1 card for “Monster Reincarnation”, or need a “Blue-Eyes White Dragon” on the field to activate the effect of “Burst Stream of Destruction”.
* Since the Spell Card itself is not activated (only its effect is), your opponent cannot chain “Magic Jammer”, “Dark Deal”, or any other card that has to be chained to the activation of a Spell Card.
* When you resolve “Destiny Hero – Diamond Dude’s” effect you
o (1) reveal the top card of your Deck, then
o (2A) send it to your Graveyard if it is a Normal Spell Card or (2B) return it to the bottom of your Deck if it’s not. Activating that Spell Card’s effect during your next turn is not activating “Destiny Hero – Diamond Dude’s” effect at that time. Even if “Destiny Hero – Diamond Dude” is not on the field during your next turn’s Main Phases, you can still activate the effect of that Normal Spell Card.
