Can you tell me the rulings for Tournament Grounds?

0. If an effect refers to a “[subtype] spell,” it refers only to a spell that has that subtype. For example, Knights' Charge is a card with “Knight” in its name and benefits Knights, but it isn't a Knight card.
1. Mana produced by the second ability of Tournament Grounds can't be spent to activate abilities, including equip abilities.
