Opinion on this Saizo build

I honestly like this guy, his stats are all around balanced besides of course his low res stat which makes up for his physical bulk. I think he has potential to be a great debuffing unit with his smoke dagger and deal consistent true damage with his Poison strike and inheriting Savage blow for small AOE damage. I plan on getting him to a 5*, but right now he's a 3* and I plan on working him up to that point so that I can greatly benefit that nice amount of SP along this journey.

Weapon: Smoke Dagger+
Assist: Harsh command
Special: Bonfire
Passive A: Fury 3
Passive B: Poison Strike 3
Passive C: Savage Blow 3

Tell me what you think, this build allows Saizo to debuff enemies around his target that he fought (Smoke dagger effects) as well as dealing a bit of damage to them as well (Savage Blow). The debuff effect from Smoke dagger doesn't apply on the target he initiates combat with, but with Poison Strike he'll do 10 true damage to them instead, softening them up for teammates to finish them.
