4/5C Control leans on sweepers and spot removal to neutralize your threats, so protecting your key creatures becomes the priority. Royal Treatment gives you an additional copy to shield a key attacker or Earthbender Ascension enabler from targeted removal at a critical moment. Pawpatch Formation provides flexible instant-speed interaction to pressure their tapped-out turns or protect creatures on their sweeper timing. The additional Surrak, Elusive Hunter gives you a resilient threat that is harder to answer cleanly and keeps applying pressure through attrition. Meltstrider's Resolve and Archdruid's Charm are trimmed since Resolve is a slower aura that can get two-for-one'd by removal and Archdruid's Charm is vulnerable to counter magic at sorcery speed.
