Tribute (転召, Tenshou) is an effect of certain spirits. Spirits with this effect have the following text:
- Tribute: Cost [X] or more → [Zone] - After paying for the summoning cost, you must send all core from one of your Cost [X] or more spirits to the [Zone].
This summoning condition cannot be bypassed, except by certain effects like The MasterDragonRider Dark-Crimson.
