Card text

Create ten 1/1 white Insect creature tokens with flying. Exile 17-Year Cicadas with seventeen time counters on it.

Suspend 17 — {0} (Rather than cast this card from your hand, you may pay {0} and exile it with seventeen time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost.)

Whenever you cast a spell, if this card is suspended, remove a time counter from it.
