New Card Batch 2

I got lots of single cards and some sealed product in my birthday, and it was enough to do a good update to my cube. Also, a handful of old favorites is back.

Added

Steel Overseer
Contagion Clasp - Introducing proliferate, hopefully the first of many.
Razormane Masticore
Will-o'-the-Wisp
Fallen Askari
Cemetery Reaper
Clockspinning
Augury Owl - Back by request.
Tezzeret the Seeker
Scythe Tiger - Buffing green aggro.
Garruk's Companion
Bestial Menace
Mishra's Factory - Essential.
City of Brass - Essential [2].
Strip Mine - Essential [3].
Crusher Zendikon - Back after a holiday. I missed a 4/2 trampler for 3 in red.
Ricochet Trap
Chandra's Outrage
Story Circle
Elspeth, Knight-Errant - I hope I don't regret this.
Saltblast


Swapped

Energy Chamber for Clay Idol
Trip Noose for Fellwar Stone - Another Icy Manipulator for a constant 15th pick.
Orochi Hatchery for Mana Cylix - A game finisher for another constant 15th pick.
Golem Artisan for Neurok Hoversail
Runed Servitor for Tanglebloom
Triskelion for Worldslayer
Curiosity for Stifle - People were scared Stifle would be useless in their decks, so it rarely saw play.
Time Warp for Wind Dancer
Vigor for Panglacial Wurm - While the Wurm is unique in its "play from the library" clause, it had to cost less for that to be relevant.
Plow Under for Wild Leotau
Howl of the Night Pack for Jolrael, Empress of Beasts - I'm a bit skeptical about the effectiveness of a card that calls for monocolored in limited.
Verdant Force for Phantom Wurm
Troll Ascetic for Phantom Tiger
Decimate for Rhox Brute - Situational, yes, but only trying it will tell how often the situation comes up.
Kirtar's Wrath for Catastrophe - Armageddon is not fun, tokens are.
Burrenton Bombardier for Droning Bureaucrats
Kor Skyfisher for Kataki, War's Wage
Swell of Courage for Mighty Leap - We need effective combat tricks, so I'm taking out one that saw little love and trying one that may decide games.
Swords to Plowshares for Second Thoughts - This one is sad because I had to take out removal, but Second Thoughts might come back in the future.
Goldenmeadow Harrier for Suntail Hawk
Stormfront Riders for Unquestioned Authority - Authority is nice, but Riders is so awesome. Unblockability is too strong in my cube, I feel.
