Two attacks are not within the realm of power of a D-tier. However, they are for a C-tier.
Adjust costs, cooldowns and etc. accordingly, if you take my advice.

Blend: This is more like B-tier skill, please tone it down a little bit, you wont get a perfect blend in D-tier skill

Save me, Bullseye: please state that you can only clash with D-tier ability for this skill (unless you use damage scaling), also please note that you cant clash with intangible attacks

Silent Strike Id suggest range scaling for this skill. Please give physical movement detail for the requirement

Mirage Throw State the damage it will deal, D-tier for each knives for this case. Id suggest to use Damage or Range scaling for this ability. Please give physical movement detail for the requirement

Catwalk: Please state that it is a solid surface (ground, rope, ice, etc)
