How it works

1. Cast Scurry Oak by paying its mana cost.
2. When Scurry Oak enters, Blasting Station triggers, untapping itself.
3. When Scurry Oak enters, the effect that adds +1/+1 counters to entering creatures also triggers or applies its replacement effect, putting at least one +1/+1 counter on Scurry Oak.
4. Scurry Oak triggers, creating a creature token.
5. When the creature token enters, Blasting Station triggers, untapping itself.
6. When the creature token enters, that same effect from step 3 causes you to place at least one +1/+1 counter on it.
7. Activate Blasting Station by tapping it and sacrificing the creature token.
8. When the creature token dies, Yuna triggers, putting at least one +1/+1 counter on Scurry Oak
9. Repeat steps 3 through 5 once.
10. Resolve the Blasting Station ability.
11. Repeat from step 7.
