How do i play as vayne against rework ashe?

Hey guys whats up. So i have been a vayne main for a while now, yes i know she’s currently considered bad in solo Q and all that jazz. Ashe has always given me a bit of trouble in lane as vayne, but if i played correctly and got a nice condemn folowed by ult on her, it usually was enough to kill her, or atleast i felt like i could somewhat trade, often times would win lane. After the Ashe rework i absolutely cannot play this match up, so i set up a custom with a friend, we made a custom match and did a 1v1 me as vayne him as ashe. I’m not a challenger vayne pro or nothing even close, but she is the champion i have the most games played with like maybe around 300 games, and my friend has maybe 5 games played as ashe, and generally does not adc ever. We played 2 games and he absolutely shit on me, while hes a great top laner and jungler i found it odd that he could beat me, so did he, it felt like i lost every trade at every point of the game (lvls 1-14). So we set up the ideal scenario, after i have Bork and berseker greaves he would let me auto, condemn him in to a wall and tumble proc 3 silver bolt, to then actually fight back, even with this utopic idealistic scenario, ashe would still shit on me o.o like...wtf happened to this champ? Like after the condem play and continued autos, with little to no effort he would bust me down to no hp and i would die ._. .... So if any of you who are higher lvl vayne players or support mains who have observed vayne players successfuly beating the new ashe, what suggestions can you give me? Like how do i lane vs ashe now? When are ashe’s power spikes? When am i stronger? When can i all-in duel her? How do you beat this champ as vayne?
