If I have 2 Viktor Leaders and one dies, does it generate a token?

Ruling: Yes, when one Viktor dies while another Viktor is on the board, the surviving Viktor will generate 1 token because Champion Units are still units and each separate card counts as an "other" unit.

Nuances:

• If both Viktors die simultaneously (such as from a board wipe), neither generates a token. When units die simultaneously during cleanup, they are all in the trash when their effects would trigger and cannot see each other die, so the effects do not resolve.
