How to buy a ticket from Tokyo to Kyoto is the most cost-effective way?

I like trains. Skyline and NEX express trains are faster.

2 Tokyo-Kyoto round trip plus some other JR, JR passes are cost-effective.

JR pass can't take the fastest Shinkansen NOZOMI-のぞみ, and can only take the slow and slow light.
