New primer is great. Some comments on it:
Talisman of Impulse, Raging Ravine, Eldrazi Mimic, Domri Rade, Wastes, SSG, and Basilisk Collar are also worthwhile options some have used.
Wolf-Run kills Phantasmal Image.
Key Weakness: Blood Moon. A couple of Mind Stones isn't going to be enough to fend it off. Sideboard options
are limited if you don't have a Noble/Bird/Mind Stone in play before Blood Moon is played. This weakness has
purported kept some pros away from playing the deck.
Key Weakness: None of the creatures on the Stock List have evasion, though the 4 Smashers have trample, and the 4 Obligators
can keep a creature from blocking.
Key Strength: The "Stock List" has a whopping 14 cards that can be played on turn 1, so the interaction/game plan starts immediately.
Key Strength: The "Stock List" has a whopping 12 Haste creatures which is awesome for recovering from Wrath or killing planeswalkers.
Key Strength: The manabase is pretty good, and not as painful as some 3-color fetch manabases.
Key Strength: Obligator gives the deck a uniquish angle of attack on the metagame. It can kill opposing Death Shadows, for example.
Other Notable: The deck does not use the graveyard, so SB options that kill all graveyards can be used.
