When Stormbound Geist dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter and a vigilance counter on it.
Activate Tayam by paying ({3} magic symbol) , removing a -1/-1 counter from Devoted Druid, and both counters from Stormbound Geist.
Holding priority, repeat steps 3 and 4 one additional time.
