Tribute your face-up Kuriboh in the field to special summon Kuriboh Tokens as many as possible. Those tokens can be used for stalling and tributes except for tribute summon. You can then use Detonate, destroy those tokens then destroy cards that your opponent controls depending on the number of Kuriboh and Kuriboh tokens destroyed by Detonate.
I used a kuriboh last gamble deck and made it immediately to platinum from silver. Even beat some Phoenix decks along the way. Deck is :
3x Darkflare Dragon
3x Thunder Dragon
Idea is to get enough cards in your graveyard to 2x special summon darkflare and multiply and detonate kuriboh to clear the field first. Then just two attacks and you win
