Due to the prevalence of spot counters for equipment (and other less common counters such as Soulreave) it's hard to rely on Bloodthirsty Blade to keep champions alive for more than a turn. However, the Multiattack can be somewhat useful in specific cases, and requiring the opponent to counter it may still be helpful.
