Combo this card's 2nd effect with "Dododo Driver", allowing you to conduct a Rank 5-7 Xyz Summon.
If you have 2 copies of this card in your hand while your opponent controls a monster and you control none, you can Special Summon one of them from your hand, then Tribute Summon the other copy. The second copy will activate its effect, allowing you to Special Summon the Tributed copy from your Graveyard, setting up for a Rank 6 Xyz Summon.
When using "Onomatopaira" in a deck, it's a good idea to include this card as well, especially if the bulk of the deck consists of "Gagaga" and "Gogogo" monsters. It makes for another search target and can easily be Special Summoned via it's effect, enabling an easy Rank 4 summon.
