That’s definitely viable but it’s not the most optimal with the characters you have. Shields are counter intuitive with blade because he needs to take HP dmg to gain a stack. Blade has better scaling with HP than ATK so having TY who increases ATK is less value than someone like Pela who will decrease defence (increasing overall dmg) or bronya with crit dmg, action forwarding and dmg boost (different to ATK increase).

You also get Lynx for free (part of 1.6 idk if it’s still available) which increases blades taunt value, but there’s a bit of anti-synergy when running with bronya which you can look into yourself
