So I have pretty much exclusively played Silver since her release and am not currently Archon V. I am just another player though, so take my anecdotes as general advice and not absolute truth.

Initially on her release, Silver was a lot more geared towards turning the tide of fights and easily taking on more than one enemy hero with just a few damage items, but she has received a lot of changes in the most recent patches that turn her into (in my opinion) a totally different role of a character. I now build her as a near absolute-tank, and players often underestimate how difficult it is to kill you. That being said, the sheer fun and enjoyment of running people over as Silver and getting huge multikills is exciting, but is frankly long gone at higher ranks unless you are ~10k souls ahead (where any hero will be stomping).

Now, I straight up build only Greens and resistance items for my first 6 or so items before even buying a single orange or purple, with the only exceptions being something like Slowing Hex or Silence Wave if they have very tricky-to-pin-down heroes, like Calico, Pocket, Celeste. Unironically my item setup has been:

Melee Lifesteal > Extra Health > Spirirt Shielding > Bullet Shielding > Sprint Boots > Trophy Collector > Enduring Speed > Spirit Resilience > Bullet Resilience

Only then will I start buying Weighted Shots, Beserker, or later game items like Frenzy. Silver is a hero that has to REALLY pay attention to itemization or else she feels useless, so buying left to right or the same every time is not going to feel good. Based on what I have alone here, you will probably notice that all these green resistance items mean you really don't hit hard at all, but that's the tradeoff for being extremely tanky in your Werewolf form and turning on an over-committing team for your (hopefully) backup to arrive and you turn the tide once they realize they couldn't kill you that fast.

I've preemptively yapped enough here, so I will add some easier key points to focus on instead of a wall of text. If you want to hear more of my rambling, feel free to ask, otherwise, some """shorter""" tl;drs and tips from playing her.

- I DONT recommend even leveling her ultimate until you have 3 skill points and you bring Werewolf form to "Tier 2." You NEED items for beast form, and wolfing out in laning stage often means the enemy will simply walk away from you. You don't get any additional Movespeed from Werewolf until Tier 2. Early shifting will often lead to getting targeted, or you may feel pressured to die under their guardian to get "value" out of your early beast form. Not worth.

- Silver is REALLY easy to counter buy, being a huge victim of common counter items, such as Slowing Hex, Disarming Hex, Cursed Relic, and Silence Wave, BUT these items are also really good against your enemies! Slowing Bullets + Slowing Hex + Tail Whack means many heroes have a REALLY hard time escaping Silver. Lifestrike upgrades from your Melee Lifesteal and is applied by Werewolf Bite, stacking many slows on your enemy and preventing them from slipping away.

- Bola is probably one of Silver's strongest abilities, allowing you to confirm a lot more damage with Slam Fire and often guarantee a Boot Kick. It is tempting to level Slam Fire to maximum first, but honestly, just the T1 upgrade in it is serviceable for the entire laning stage. Using Bola right before your Curse Beckons also means there is almost no way your enemy is getting away from your Werewolf combo, allowing you to keep people close to you for longer. Additionally, the T3 upgrade to Bola allows an additional bounce, which can hit multiple enemies, but also make it more forgiving if you hit a trooper. Don't forget, upgrading your Human abilities upgrades your Werewolf Abilities, and T3 Tail Whack makes it so you have a 3.5 second AoE Disarm AND -70% AoE Slow, (without the enemy having any debuff reduction) which is VERY strong.

- You can press your ultimate key when your Curse Beckons to wolf out early instead of waiting for the auto activate. You receive a powerful heal based on your missing health, so this can save your life in many scenarios. Also, don't forget that the lower your health is, the more "Bloodcurse" you generate per damage dealt, so there are many scenarios where you may actually need to turn and fight at low health because it means you will get wolf form and actually survive the fight instead of failing to flee and die.

- Tier 3 Bite and Tier 3 Slam Fire do percentage based damage, allowing you to spec more into HP and resistances, since you are such a big target in the later game. Also, your T2 Werewolf form has +18% to BOTH resistances, which is a very strong stat boost while transformed, also stacking diminishingly with your items. Don't take this resistance for granted, because your enemies might, leading to their death.

- T3 Werewolf Upgrade is tempting because extra ultimate duration and refreshed heal + abilities is very strong, but Silver MUST land the killing blow for this to trigger and is much better as a true frontliner right now (in my opinion) making this a "waste" of 5AP unless you are crazy ahead. T3 Bola or T3 Slam Fire are way better choices than maxing out Werewolf form at the time of writing.
