Need Help with My Atraxa +1/+1 Counters Deck

Hi everyone,

This is my first time building a deck from scratch to play in my casual POD, and I‘m working on an Atraxa +1/+1 counters deck. I don’t want to include infect or poison mechanics.

I’m currently at 103 cards, and I’d love your suggestions on what to cut or replace. Additionally, I’d like to avoid game-changing staples like tutors, Cyclonic Rift, or other high-power cards that fit into any deck.

I’m aware my mana base could be improved, but lands are quite expensive. Unless there are solid budget-friendly upgrades, I‘m okay with keeping them as they are for now.

Thanks in advance for your help!
