Th Return to Ravnica block has the following set names:
- Return to Ravnica
- Dragon's Maze
The original Ravnica block had the following set names:
- Ravnica: City of Guilds
Notice anything? Set #1 in each block begins with an "R," Set #2 begins with a "G," and Set #3 begins with a "D."
Just thought that was somewhat cool and figured I would share.
