Ipsumancy

When a homunculus die, put a ipsum counter on Ipsumancy.
Creatures you control have reaction X. (When this creature dies in combat, it causes X damage to the creatures that dealt damage to it. Where X is the
number of counters on Ipsumancy. If a creature has multiple instances of reation, each triggers separately.)
Erase, build, extinguish, resurrect, obliterate. Repeat.
