This clever loop relies on Technomancer and Phyrexian Metamorph continuously copying each other from the graveyard through their shared entry triggers. Because Phyrexian Metamorph can enter as a copy of Technomancer with a mana value low enough to meet the original's return restriction, it effortlessly rebuilds the loop each time. To turn this mechanical recursion into a decisive win, Goblin Bombardment steps in to effortlessly sacrifice the cloning creature in response to its own trigger, converting the endless cycle of artifacts entering and leaving the battlefield into infinite damage against any target.
