This card can be discarded as cost for a lot of cards or effects, in order to replenish its owner's hand.
A nice option of discarding effect to pair with this card would be "XYZ-Dragon Cannon", as it would provide three further discard fodders for its effect (the three Ojamas themselves).
It can also be combined with "Snipe Hunter" to get more discards for its effect. It can also be discarded with "Summoner Monk" to Special Summon "Snipe Hunter" from the Deck and still have three cards to discard for its effect.
In an Ojama-centered deck, discard this card for the effect of "Ojama Country".
