I'm really not sure here. Blow, Tilling, Market, and Denizen are our on-color options, and we can eliminate Market and Blow out of hand (Market is far too expensive and Blow has almost no worthwhile targets, even coming out of the sideboard.) I do agree with Tahn in saying that the Denizen has the highest chance of making our deck, but that chance is very near zero, and Tilling does send a better signal.
Maybe we should just cheat and take a Mugging. (jk, jk)
The trigger looks at Zegana as she last was on the battlefield to determine how many cards you'll to draw. Assuming the removal wasn't something that changed her power (like Dismember), you'll draw 5 cards.

No, since you're not casting the dragons that you get off Vol.

(doubt we'll really be needing 5-mana enchantments)
Correct. Replicate just copies the spell on the stack; the copies aren't cast.
Look in the spoiler.
Extort doesn't actually deal any damage, so Divine Reflection won't do anything.
Personally I like Team Duskmantle.
