So here's an inkling of the kind of stuff I'm considering for the Zegana list that either replaces all black stuff or swaps with current Simic stuff. It won't all fit, but what I do will make this a lot tougher. I add this in case you have some pet cards you wanted to suggest. All ideas welcomed.
Zegana (formerly damia)
+Farseek
+Sylvan Scrying
+Spidersilk Armor
+Sleep
+Polymorphist's Jest
+Theft spells from blue
+Mystic Snake
+bounce
+Turn to frog
+Pongify
+Beast Within
+Eaten By Spiders
+Arachnogenesis
+Silklash Spider
+Emerald Medallion
+Sapphire Medallion
+Sky Diamond
+Moss Diamond
+Capsize
+both Kiora cards
+Aether Mutation
+Whispersilk Cloak
+Lightning Greaves
+Empyrial Plate
+Kiora's Dismissal
+Hurkyl's Recall
Instead of grafting, consider evolve creatures with a couple of grafters
+Clone
+Vesuvan Doppelganger + other shaleshifters
+UG creatures like Simic Sky Swallower and good legends
+Curse of the Swine
+Rapid Hybridization
Note: will make this more browser friendly tonight.
