6 rulings from Wizards of the Coast
- 2 October 2025Once you announce that you're casting a spell, no player may take actions until the spell has been paid for. Notably, opponents can't try to change by how much The Great Henge's cost is reduced.
- 2 October 2025The cost reduction ability reduces only the generic mana in The Great Henge's cost. The colored mana must still be paid.
- 2 October 2025To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell remains unchanged, no matter what the total cost to cast it was.
- 2 October 2025Once The Great Henge's last ability has triggered, you'll draw a card even if you can't put a +1/+1 counter on the creature for some reason (most likely because it has left the battlefield).
- 2 October 2025The first step of casting a spell is to move it to the stack. If this causes the greatest power among creatures you control to change, that new power will be used to determine the cost reduction.
- 2 October 2025Once you determine the cost to cast The Great Henge, you may activate mana abilities to pay that cost. If the greatest power among creatures you control changes while activating mana abilities, the cost to cast The Great Henge remains what you previously determined.
