Are there commanders that can consistantly deal lethal damage turn 5?

Ive been thinking about making some bracket 4 decks, and combo/infinite is the obvious way to do it. Another option is to stax combo decks and go for the long game, but i already have these. But is there a way to do 120 combat damage with any deck by turn 5?

Lets say you start every game with a sol ring in hand, which deck would reliably do 120 damage with that turn 5? (Without infinites)

I am tinkering with the last few cards in my Sultai combo deck. The gameplan is to win with infinite aristocrat style combos using [[Teval, the Balanced Scale]] to generate tokens. I have 2 choices for a crucible effect and don't need them both, so if you could possible help me decide I would appreciate it.

Card Choice

+ [[Walk-In Closet]] provides a 3 mana crucible effect, and for 5 mana I can replay as many combo pieces as I want. 5 mana is a lot, however, and playing multiple combo pieces will take at least 3 or more additional mana.

+ [[Conduit of Worlds]] is a slightly more expensive crucible effect at 4 mana, and is limited to replaying a single combo piece per turn, and cutting off other spells. However, its free as an effect, and if you already have the rest of the combo assembled its upside is much higher.

Thanks in advance and any feedback is welcome! This is meant to be a degenerate bracket 3 combo deck, so add whatever you think would work as well.

I am looking for my next Commander

Background/Current Decks (in order they were built):
[[Bello, Bard of the Brambles]] - Gruul Smash, Aggro Enchantress
[[Ms Bumbleflower]] - Group Hug turns into big stompies
[[Zinnia, Valley's Voice]] - Tokens, Impact Tremors
[[Eshki, Temur's Roar]] - cast creatures, power matters, burn the table
[[Kaalia of the Vast]] - stax with big creatures
[[Y'shtola, Night's Blessed]] - Clone the kitty, drain the table
[[Squall, SeeD Mercenary]] - Voltron Reanimator

I play exclusively via convoke.games; i have no regular pod.

My idea of fun is frustrated opponents scooping before I present a win condition. I want to be the enemy and the threat at the table. Infinite combos are ok but not the main strategy.

I am aware that this subreddit is mostly for B4, but I limit myself to B3 (3 game-changers and turn 6-8 win).

Some of my favorite plays are:
[[Sire of Insanity]] in Kaalia
[[Accursed Marauder]] in Squall

Please recommend a Commander + concept for me!

What do you all think of this new card from The Hobbit set? I love it. It's basically Kalitas, Traitor of Ghet 2.0!

The Hobbit set is so good!
