Frogspawn Jumper

{t}: Add {u} or {g}.
Whenever Frogspawn Jumper is tapped for mana, choose one:
• Create a 1/1 blue frog creature token with "This creature can't be blocked.".
• Create a 1/1 green insect creature token with flying.
As long as you control 7 or more creature tokens, Frogspawn Jumper has reach and "This creature can't be blocked.".
Frogspawn Jumper's power and toughness are each equal to the number of token creatures you control.
