Spice Blow

At the start of your upkeep, place a charge
counter on Spice Blow.
If Spice Blow ever has four or more charge
counters on it, gain a Spice Token for each
charge counter on Spice Blow, then sacrifice
all charge counters on Spice Blow.
Whenever a Sandworm creature you control
enters the battlefield, place a charge counter
on Spice Blow.
