Loop

A loop describes a set of actions that could be repeated indefinitely.

Loops need to produce something per rotation to be useful, such as:
 * Infinite mana (Freed from the Real + Axebane Guardian + any defender)
 * Infinite tokens (Midnight Guard + Presence of Gond)
 * Infinite life
 * Infinite damage
 * Infinite storm count

Once a rotation is established it might be possible to take shortcuts.
