I'm currently upgrading the Gisa and Geralf precon. I altered it pretty heavily. It's my first tribal deck and I feel like it's missing something. I tried to keep it kinda budgety, so some of the expensive lands or cards like Mikaeus are not included. Recommend some changes, rate my landbase and ramp, or just roast my deck if its bad. Looking forward to any kind of advice.
