    What to cut / what to add

    These swaps keep the deck focused on building a creature board and attacking, rather than shifting to a different strategy. The package prioritizes mana development, sustained card flow, and interaction so the deck isn't relying on size alone. Cutting creatures does mean giving up potential power toward Ghalta's casting discount, but those slots need to support the whole game plan, not just make the commander cheaper. Challenger Troll and Dungrove Elder leave as part of that trade-off. At $82.34, the ten additions target supporting roles while preserving the deck's creature-heavy core.

    Tramplesaurus Rex FAQ

    Frequently Asked Questions

    It's worth considering if you enjoy large creatures and a straightforward combat plan. Out of the box, its creature-heavy build supports Ghalta's casting discount, and Ghalta's trample helps push damage through blockers. The upgrade plan identifies mana consistency, ongoing card flow, and interaction as areas to improve. The roughly $82 of swaps on this page address those weaknesses without changing the deck's main approach.
    Ghalta, Primal Hunger leads the deck. Ghalta costs {X} less to cast, where X is the total power of creatures you control, and has trample. That gives you a clear reason to develop your creature board before casting your commander.
    The supplied prices total $82.34 for the ten additions. Greater Good is the lowest-priced addition at $1.62, while Guardian Project is the highest at $15.37.
    No. You're still building a board of creatures, using their total power to reduce Ghalta's casting cost, and looking to win through combat. The swaps focus on the support around that plan rather than replacing it.
