A new Item card has been revealed from SM5 Ultra Sun and Ultra Moon! Thanks goes to Vincent for the translation!
You may play 4 Missing Clover at the same time. If you play 1 Missing Clover, look at the top card of your deck. Then, put that card back. If you play 4 Missing Clover at the same time, take a Prize card.
You may play as many Item cards as you like during your turn (before your attack).
It’s called “Missing” Clover because it’s only one of the four leaves. When you put four of them together, you get a lucky four-leaf clover.
