Gruul Ponza leans on ramp and land destruction (Mwonvuli Acid-Moss, Thermokarst) alongside threats like Writhing Chrysalis and Colossal Dreadmask; Thraben Charm can destroy their ramp enchantments or remove creatures like Writhing Chrysalis. Sprouting Renewal gives you a second flexible answer that can destroy an artifact or enchantment or create a body. Since this deck can fall behind on lands, keep pressuring aggressively and use your answers reactively rather than proactively. Maintain the low curve to punish their ramp-heavy, land-light hands.
