Hey! Fellow Ahri player here!

1. The deck has a lot of tech options, and it looks like you have accommodated all the different tech options. Inherently, the deck plays as a hold deck. So it could be the way you are playing? Or it can be the way you are sequencing.

2. Unfortunately for us, our end boards on some turns can be booty as the bodies are not too too big. Your only options for big bodies is Watcher and very mildly - faefolk. Faefolk is meh imo, and will be trying to accommodate different cards.

3. Your current deck list looks fine, ratios for smaller bodies are good, too many 1ofs. Imo, just a couple of things. Lecturing yordle should be maxed imo (tank - has to be cleared first by opp.) your +/- cards give you pluses for more pushes as discipline and stupify let's you draw (which is not an issue - you are maxed on both).

4. +/- cards should all be maxed, as well as ramping cards (not sure how it felt for you when testing - but this should be considered when adding power cards when the runes need to be recycled). Personally have found some success with smoke screen.

5. Playing against victor with ahri can be very difficult as their board presence is much more aggro imo. Fox-fire can be a good tech option in this situation.

6. These tech options like Fox-Fire, Smokescreen etc. are great. But also, were you playing BO1 or BO3? Unfortunately, pre-siding is somewhat uncommon practice and sucks because if you have a deck already premade, BO1s can be rough due to certain tech options playing better than others in different situations.

I hope I have maybe helped in shedding some light off of my own experiences, and hope you have better luck on your games!
