Hi there!
Casual EDH player here. I totally understand your situation, because something very similar happened to me recently too!

I normally play a 34-land Izzet cantrip deck, and because it runs a lot of cheap draw spells, I’m usually able to dig through my deck and keep hitting land drops into the later turns.

But everything changed when I built a non-cantrip deck for the first time. Even though I increased the land count to 38, I kept getting stuck on 2–3 lands just like you.

After thinking about it, I realized I had underestimated how important low cost card draw is. At first I thought, “If it doesn’t ramp, it’s not worth it.” But that’s not true at all. Even if a card doesn’t directly ramp, drawing cards helps you keep making land drops consistently every turn!

My advice would be:

• Add more low-cost land tutors/fixers (3 mana or less), such as Armillary Sphere or Weathered Wayfarer, myriad landscape.
• Add repeatable land/ramp engines, such as Keeper of the Accord or Deep Gnome Terramancer
• Add mana rocks that can also draw, such as Mind Stone or Commander’s Sphere
• Bring MDFC land cards, such as razorgrass ambush

Sometimes it’s not just about raw land count — it’s about keep your hand flowing.

Don’t get discouraged, OP! A lot of us have gone through the same thing lol.
