Time Elemental returns The One Ring to hand for 2UU; recasting it for 4 resets the protection-from-everything trigger at the start of each loop. The lock runs through any blue Commander shell that can keep Time Elemental alive — the 0/2 body is the fragile half, since a single removal spell before activation collapses the whole engine.

Variations

Cheaper, tighter, alternate lines

Erratic Portal and Crystal Shard do the same bounce job at cheaper activation costs, cutting the per-turn mana investment significantly — drop Time Elemental for either if the deck runs colorless mana. The loop prevents damage but does nothing about opponents winning through mill, poison, or alternate win conditions, so pair it with an actual threat rather than treating it as a standalone lock.
