For a Dark world Deck YUGIOH?

Question

hey do you guy recommend putting the card "Final Destiny" which is spell card in a dark world deck. What the card dose is discard 5 cards from your hand and destroy all card on the field. I think with this card you can do a 1 hit KO with a dark world deck tell me what you guys think

Answer 1

Final Destiny's effect requires that you discard 5 cards as the COST to activate the card's effect, so Dark World monsters will not gain their effect if sent to the graveyard by Final Destiny.

If Final Destiny stated:

Destroy all cards on the field, then discard 5 cards from your hand.

Dark World could use it to special summon themselves if it stated the aforementioned text but as it stands they cannot.
