Mega cycle

A mega cycle is a cycle with its member cards distributed across separate sets. When these sets are spread across multiple blocks, this is sometimes referred to as a mega-mega cycle.

Three-card mega cycles
One card per set within one block.

Guild mega cycles
Ravnica's design is based upon the use of all ten two-color combinations in the forms of guild, and its popularity has resulted in multiple set revisits. As such, mega cycles are prevalent, even after the shift to leave small sets and yearly blocks behind.

List of mega-mega cycles
A mega-mega cycle (a.k.a Supercycle) is a cycle with its member cards distributed across separate sets; unlike a mega cycle, however, these sets are not all within a single block but are from multiple blocks.

Double mega-mega cycles
Many land cycles are double mega-mega cycles which started in one set and were completed in another.
