You want too much. Focus on what you want best, build a deck around that concept, playtest it, look for flaws, patch the flaws, reassess your deck, rinse and repeat. Trust me, your decklist will change more often that your pants if you're really active in the game.
Experiment Kraj is an obvious one, but it's pretty cool regardless. Zegana herself is also quite nice, especially if you could transfer her counters onto something else, sac her, replay her.
To start with, you might want to check out the stickied threads in the EDH section.
You want EDH to be fun? Just make sure you grasp the general concept of the game then build your deck! No need for guides. That's how some EDH players started. Then you just adjust your deck to make it better as you go and play.
I can kill vorinclex with no problems. There goes your mana advantage, amigo, but how do you answer an epic ramp spell? Mana is a HUGE advantage in commander (and in any other format, I guess) and the most feasible way to equalize the board is by using mass land wipe. But then do a mass land wipe and the whole table turns on you. So yeah, I voted for boundles realms...
2 cmc, so a good cost for aggro
2 power for 2 cmc, ok...
2 toughness (at least doesn't die to gut shot, and yes, I know, it dies to TONS of other cards.)
graveyard cast hate
FIRST STRIKE (VERY red)
HASTE
This card CAN find a home in Standard RDW, if in case that deck becomes viable in Standard.
Well, people actually spend money to bust boosters, so finding a rare that's just not worth it will disappoint people. I personally prefer booster-busting than singles hunting...
I don't think that azorius mythic would be played outside limited and edh. Fits the guild theme, though. I crack one, I'll PROBABLY put it in my ruhan EDH deck.
Why sac her (tax hurts) when you can bounce her? Stampeding wildebeast ans stampeding serow comes to mind
