Multikicker {1}{G} (You may pay an additional {1}{G} any number of times as you cast this spell.)
Joraga Warcaller enters the battlefield with a +1/+1 counter on it for each time it was kicked.
Other Elf creatures you control get +1/+1 for each +1/+1 counter on Joraga Warcaller.
The last ability counts the total number of +1/+1 counters on Joraga Warcaller, not just the ones placed on it as a result of its enters-the-battlefield ability.
