A lot of people seem to write off Geralf as a commander for a weak mill deck or mono blue zombies. However I like the more interesting combo-like idea of running lots of blue fatties for Geralf to mill, to get large zombie tokens early on. There is also artifact ramp and ways to cheat creatures into play in case you actually want to cast your fatties. Here is the list:
1x Artisan of Kozilek
1x Body Double
1x Breaching Leviathan
1x Burnished Hart
1x Consecrated Sphinx
1x Frost Titan
1x Grozoth
1x Havengul Runebinder
1x Inkwell Leviathan
1x It That Betrays
1x Kraken of the Straits
1x Lorthos, the Tidemaker
1x Pathrazer of Ulamog
1x Pearl Lake Ancient
1x Phyrexian Dreadnought
1x Platinum Emperion
1x Quicksilver Gargantuan
1x Sakashima the Impostor
1x Scourge of Fleets
1x Solemn Simulacrum
1x Soul of New Phyrexia
1x Stormtide Leviathan
1x Tidal Force
1x Tromokratis
1x Ulamog's Crusher
1x Caged Sun
1x Coalition Relic
1x Extraplanar Lens
1x Feldon's Cane
1x Gilded Lotus
1x Illusionist's Bracers
1x Lightning Greaves
1x Magewright's Stone
1x Quicksilver Amulet
1x Rings of Brighthearth
1x Sensei's Divining Top
1x Sol Ring
1x Swiftfoot Boots
1x Sword of Light and Shadow
1x Thran Dynamo
Sorcery (5)
1x Grasp of Phantoms
1x Ponder
1x Portent
1x Time Ebb
1x Time Spiral
1x Rhystic Study
1x Training Grounds
Instant (9)
1x AEtherspouts
1x Cyclonic Rift
1x Ether Well
1x Griptide
1x High Tide
1x Hinder
1x Memory Lapse
1x Psychic Spiral
1x Submerge
Land (43)
1x Academy Ruins
40x Island
1x Maze of Ith
1x Reliquary Tower
I think the deck could probably use more non-basic lands but I'm not too sure on what to add. I would love to hear everyone's thoughts on the list!
