I believe you get it wrong on Swamp Thing. Tom King only write Swamp King on Winter Special. The Writers on Swamp Thing during the New 52 are Scott Snyder and Charles Soule, but you are on point on Snyder and Soule did a hella job on writing Swamp Thing during the New 52. Especially Charles Soule. His Swamp Thing is second only to Alan Moore and that is saying something with how many big writers already written Swamp Thing.
