The big question is whether its worth playing over the Energy-filled Elephant in the room
For me, option #2 is the easy choice, and I hope to convince you the toxic sweetness that is a fine-tuned Poison deck
This deck played around 20 enchantments to get triggers off his cast ability to make his legendary fun, like Rhystic Study and Sylvan Library, around 15 Frogs and changelings to use his ability on like Yargle, Glutton of Urborg and The Gitrog Monster and then some Voltron-ish and unblockable elements to get some punches in like Archetype of Imagination and Whispersilk Cloak
Komainu Battle Armor will take advantage of someone whos left only one creature back to block, since it has/grants menace
Your enhancements also are easy to kill and dont stick like Honor of the Pure or Thalias Lieutenant
If you need a defensive monster, give it deathtouch and lifelink
