Gruul Ponza uses Mwonvuli Acid-Moss and Thermokarst to destroy your lands while ramping into Annoyed Altisaur and Avenging Hunter, so the extra Ram Through lets a pumped hexproof trampler fight through their bigger creatures for value. Aqueous Form provides evasion to keep your clock consistent even if they take the initiative via Avenging Hunter or stabilize with a big blocker. Cut Cartouche of Solidarity and Sentinel's Eyes since going wide matters less than pushing damage through their few but large blockers. Be mindful of land destruction disrupting your mana for Ancestral Mask and Utopia Sprawl, so prioritize casting your enchantments efficiently before they can strand you on lands.
