I agree that it depends on the meta. Goyfs are great when you expect a field full of non-UW fair decks and bob is spectacular otherwise. Me, I've just started testing x3 young pyromancer + volrath's stronghold in Hoogland's old bob list (replace bob w/ pyromancer) and it's ... very, very powerful once you get loam and/or pun fire going. Will probably keep going with this =).
The list:
1 Badlands
1 Bayou
1 Dryad Arbor
1 Forest
1 Karakas
1 Maze of Ith
1 Nantuko Monastery
1 Savannah
2 Forgotten Cave
2 Grove of the Burnwillows
2 Taiga
2 Tranquil Thicket
4 Wasteland
4 Wooded Foothills
1 Gaddock Teeg
4 Knight of the Reliquary
4 Chalice of the Void
4 Mox Diamond
2 Sylvan Library
3 Abrupt Decay
3 Punishing Fire
1 Green Sun's Zenith
2 Devastating Dreams
3 Life from the Loam
4 Burning Wish
3 Young Pyromancer
1 Volrath's Stronghold
1 Bojuka Bog
SB: 1 Thoughtseize
SB: 1 Shattering Spree
SB: 1 Perish
SB: 1 Maelstrom Pulse
SB: 1 Dreadbore
SB: 1 Chainer's Edict
SB: 3 Thalia, Guardian of Thraben
SB: 1 Life from the Loam
SB: 1 Devastating Dreams
SB: 1 Gaddock Teeg
SB: 1 Ethersworn Canonist
SB: 1 Reverent Silence
SB: 1 Slaughter Games
Reverent Silence stays in sb because of my UW-dominated local meta ... it + shattering spree are all-star wish targets ... also put morningtide in sb one friday tournament due to 2 reanimator + dredge decks being there and it was an all-star as well
