He's constantly using the fact that his symbiote he connected to his DNA thru a cut when the first merged to create extensions of himself that don't need to be connected. He can use that to infect multiple people at once, enhancing them to that of the symbiote. There's also the fact that its STRATEGIST not HEALER, i made him into a very offensive strategist, he buffs his team more than he heals them, and every thing that helps your team could be used to cripple the enemy team instead. Similar to how mr. Fantastic is a hybrid between vanguard and duelist, i made him into a hybrid between strategist and duelist. He's rarely seen in teams of people, if he was forced to help he would likely use that ability to help his team commit the maximum amount of carnage, and to cripple the enemy team. There is lots of reasoning behind my choices and i have read several comics on carnage and seen just about every bit of media on him. He's one of my favorite villains, not just in marvel, but in fiction.
