Which support agent can benefit Astra Yao's w-engine the most? (other than Astra herself)

Couldn't resist myself from pressing the 10x pull once and accidentally got her weapon😭🙏.(Im planning to skip her so i can pull Qingyi and her weapon for my Zhu/Nicole team) I was at 70 pull before guarantee so i didnt waste that much luckily.

But the question is, which support agent could synergize best with Astra's w-engine.

Note:I won't pull for Astra as I love Nicole more and Anby just sucks rn so i want Qingyi
