Can either get a Kuriboh to your hand or special summon from your deck.
If you already have Multiply, and Detonate in your hand, then you can destroy 3 of your opponent's cards right away without using your normal summon for the turn. Only if you don't have a monster out on the field.
The Kuriboh support/combo is using Multiply and Detonate. They are both quick-play spell cards so you can use them in your turn right away, or during your opponent's turn. You can normal summon your Kuriboh, when/if your opponent targets your Kuriboh with a spell card, you can chain it with Multiply for protection. Activate Detonate if you want to destroy your opponent's monster or backrow.

nope not ironically 3x kuribo 3x winged kuriboh 3x flutes 3x golden apples 2x detonate 1x multiply 1x sky scourge enrise 1x dark necrofear 1x card guard and 2x dunames. pretty much you just stall until you get to like 6 cards left in the deck. the kuribogs will let you choose what damage you want to take to activate a really strong golden apple, then summon enrise + necrofear for banish + otk
