Forum:A question because i got no answer found on this website!

I got as example active "Forced requisition"

Effect of forced requisition:

You can activate this card when you DISCARD from your hand. After that, each time you DISCARD from your hand, your opponent must also DISCARD the same number of cards from his/her hand.

And i play as example "card destruction" does it work then? Effect of card destruction: Each player DISCARDS  their hand and draws the same number of cards they DISCARDED.

And for morphing jar? Effect of morphing jar: FLIP: Both players DISCARD their hands. Then both players draw 5 cards.

And for morphing jar #2? Effect of morphing jar #2: FLIP: Return all Monster Cards on the field to their respective Decks and shuffle them. You and your opponent then pick up cards until you both have the same number of Monster Cards that were returned to each Deck. Special Summon the Level 4 or lower monsters to the field in face-down Defense Position. The rest of the cards picked up are DISCARDED to the Graveyard.

And for serial spell? Effect of serial spell: Activate only when you activate one of your Normal Spell Cards. DISCARD  all the cards in your hand to the Graveyard. The effect of this card becomes the same as the Normal Spell Card.
