By this point you have Angelic Exaltation out and a decent amount of creatures to help power it's boost. Use your Dreadmalkin's ability on the Hunted Witness's (paired with Kaya's Ghostform for optimal usage), or another non-essential one drop to power him up. Dreadmalkin and Rising Populace are your heavy hitters, I usually keep Rising populace back as a defender that gets pumped up each time something dies on my side (often due to sac's). But if you are low on health, use Healer's Hawk to gain large amounts of Life back since most don't have flying defense (or alternatively one of the charmed strays). You'll be swinging with one creature each time, to get Angelic Exaltation's boost. This means you'll have plenty to block with if you don't have Mana to use Law-Rune Enforcers ability to control their board, as well as Spark Harvest.
