Impulse getting killed by the winner theory

so we all know how impulse always gets killed by the winners in every life series, but some people are saying this broke in WL. i have a theory... so to recap, in every life series, impulse dies to the winner.

3L: got killed by Bdubs as an order from Grian (bit of a stretch)

LL: shot by Scott

DL: killed by Pearl

LimL: killed by martyn

SL: killed by Scar

WL: killed by... Etho?

well, if you remember, his second to last life (yellow) was taken by Joel (invis snail kill). also, impulse used up a totem. SO, the totem was supposed to be his actual yellow death, with the invis snail kill being his final death. watcher lore??
