Yes. He's real fun and effective with right team but unfortunately one part of that team is somewhat broken right now as Aces High's Do or Die seems to not be working for me in removing the Perfect Ghost status like it does for the magus Lord of Light. If however it's intended to work like this and make the target of Ghost Blade truly unkillable for 2 turns then no it's not worth sharding him in my opinion. Opinion may change if I find another team combo but...
As it is on day one he worked great with aces, the green bat with energy and invisibility and the allied general with energy and strike to maximize power gain. Ghost blade every turn, Aces Do or Die and invisible and invincible AoS to keep everyone alive. Doesn't work against every team especially reds but hoo boy is it ever effective - and fun- against lots of defenses.
