Alice, the Spirit of Joy

When Alice, the Spirit of Joy enters the battlefield, put a joy counter on it.
{t}, Remove a joy counter from this card: This creature's controller screams "Eoeoeoeo" to target
sad player. That player answers "Eoeoeoeo".This
is repeated until target player stops being sad.
"Eoeoeoeoeoeoe" (To make this world joyful,
let your heart overflow with joy.)
Alice, the Purifier of Sadness.
