[Summon Condition: You must have 1 or more Yellow spirits on your field.]
Ultimate-Trigger [LV3][LV4][LV5] (When Attacks) When Ultimate-Trigger hits, during this battle, 1 opposing Spirit gets -5000 BP. If this Ultimate is blocked by opposing Spirits, move 1 core from opponent's Life to their Reserve. (Ultimate-Trigger: Put 1 card from your opponents deck to the trash. If the cost of that card is lower than this ultimate, it will hit)
If you sing, it doesn't matter if you're a child or if you're an Ultimate. Here, sing with big sis. ♪Round and yellow~
The one card put into Trash by Ultimate-Trigger cannot be stopped by anti-deck destruction as they have different wording in Japanese. It also cannot be increased by Charge.
