I was thinking about Rabooka and his rumoured niche purpose as a suicide bunny. According to leaks which are not confirmed yet, he kills an enemy 100% but in so doing kills himself (I always suggested Rabies should have had this kind of move).
Rabooka would bring back into the metagame the benefits of 'Immune to Instant Death' (like Demise), but are Artefacts immune to instant death, as this is not really control or DoT? @Carlos
