Veyran lacking offense?

Been playing with my [[Veyran, Voice of Duality]] deck for a bit, she’s my baby. The thing is, she is slow as hell and can’t seem to close out games. When I play this deck, I tend to get smacked around as collateral damage while everyone else does impactful things, and any time I try to build up an actual board state I get archenemied and wiped to the point where I can’t close.

Any suggestions for how to improve? (Sideboard is things I’ve taken out. “Considering” is things I don’t own, except Zara.)
