Need some commander deck building help (New to commander ^_^)
So, I play pretty casual commander at my local shop. The guys I play with usually have some bracket 3/4 decks. I am very new to commander and physical magic in general (played mtga for years) and I'm trying to build some cool commander deck that mainly follow a strategy I love but is also quite competitive: I don't care about being the strongest or winning most game, I just wanna be relevant in the game and maybe win a game every idk ten. Currently I'm going with a mega budget boros lifegain control (yes, money is another problem for me) using Bre as the commander to generate value and just removing and controlling the board with board swipes (little board wipes that keeps Bre alive and big ones) and single target removal that benefits a lot from instant and sorcery lifelink), and I think I'm currently lacking a win condition: I don't think I'm dying anytime soon but also I'm never winning. Also I'm mainly playing 2 mana rocks so I get to cast Bre on turn 3 instead of turn 4, I thought that playing 3 mana rocks was kinda useless since I wanna drop Bre as soon as possible. So yeah I'm not looking to turn this deck in a death machine, just looking to have fun by having an ok budget deck with a strategy I love, which is boros control.
This is the current deck (will get updated, and Is not yet finished):
