Elfball (EDH / Commander) [Revision 18]

General game plan:

1. Generate infinite mana
2. Either get Glacial Chasm out or generate an obscene amount of health
3. Cast Hurricane or Squall Line for lethal

Infinite Combos follow the pattern: Untapper + Big Mana Generator

Untapper Combinations

1. Umbral Mantle + 4 mana generated
2. Sword of the Paruns + 4 mana generated
3. Voltaic Construct + Liquimetal Coating + 3 mana generated
4. Temur Sabertooth + Lightning Greaves OR Swiftfoot Boots OR Thousand-Year Elixir + (3+Equip+CMC of dork) mana generated
5. Temur Sabertooth + Wirewood Symbiote + (4+CMC of bounced elf) mana generated
6. Wirewood Lodge + Argothian Elder + 2 mana generated (land only)
7. Devoted Druid + Umbral Mantle OR Ezuri, Renegade Leader + Joraga Treespeaker at Level 5 OR Leyline of Abundance OR Nyxbloom Ancient

The following are the minimums needed to hit these mana thresholds. Obviously larger values work with smaller categories.

Dorks that may generate 3 mana for Voltaic Construct + Liquimetal Coating

1. Elvish Abberation OR Llanowar Tribe
2. Incubation Druid with Adapt
3. Fyndhorn Elder OR Greenweaver Druid OR Joraga Treespeaker at Level 1 + Leyline of Abundance
4. Any dork + Nyxbloom Ancient
5. Elvish Archdruid OR Priest of Titania OR Viridian Channeler + 2 other elves
6. Marwyn, the Nurturer OR Viridian Joiner + total power 3
7. Karametra's Acolyte + total devotion 3

Dorks that may generate 4 mana for Umbral Mantle or Sword of the Paruns

1. Elvish Abberation OR Llanowar Tribe + Leyline of Abundance
2. Incubation Druid with Adapt + Leyline of Abundance
3. Elvish Archdruid OR Priest of Titania OR Viridian Channeler + 3 other elves
4. Marwyn, the Nurturer OR Viridian Joiner + total power 4
5. Karametra's Acolyte + total devotion 4

Dorks that may generate 5 mana for Temur Sabertooth + Wirewood Symbiote combo with a 1-drop

1. Elvish Archdruid OR Priest of Titania OR Viridian Channeler + 4 other elves
2. Marwyn, the Nurturer OR Viridian Joiner + total power 5
3. Any 2+ mana dork with Nyxbloom Ancient

Dorks that work with Temur Sabertooth + Boots combos

1. Priest of Titania + 4 (Thousand-Year Elixir or Lightning Greaves) or 5 (Swiftfoot Boots) other elves
2. Elvish Archdruid + 5 (Thousand-Year Elixir or Lightning Greaves) or 6 (Swiftfoot Boots) other elves
3. Viridian Channeler + 6 (Thousand-Year Elixir or Lightning Greaves) or 7 (Swiftfoot Boots) other elves
4. Any 2+ mana dork with Nyxbloom Ancient (Greenweaver Druid and Fyndhorn Elder don't work with Swiftfoot Boots)

Lands that work for Argothian Elder + Wirewood Lodge combo

1. Nykthos + 3 additional Devotion to Green
2. Lotus Field
3. Itlimoc, Cradle of the Sun + 1 additional creature
4. Forest + Nyxbloom Ancient

Ways to not die to Hurricane or Squall Line

1. Glacial Chasm
2. Essence Warden + Temur Sabertooth combos
3. Weather the Storm + Storm Count from Temur Sabertooth combos
4. Wellwisher + Excess infinite mana from untapper
5. Die anyways, it'll be glorious.

Ways to dig for the win condition
Green has no way to tutor for instants or sorceries. So, we have to rely on raw draw. The draw package is designed to be repeatable once infinite mana is assembled, mostly through Temur Sabertooth shenanigans. Beast Whisperer, Soul of the Harvest, Primordial Sage, Zendikar Resurgent, and Lifecrafter's Bestiary all draw the entire deck with a Temur Sabertooth combo out. Regal Force and Voice of Many both can draw chunks of the deck in a similar vein. Return of the Wildspeaker draws the entire deck following an Umbral Mantle combo or sufficient bounces with Marwyn, the Nurturer out.

Obvious budgetless considerations for deck in no specific order

1. Gaea's Cradle
2. Staff of Domination
3. Borrowing the East Wind
4. Selvala, Heart of the Wilds
5. Craterhoof Behemoth
6. Eladamri, Lord of Leaves
7. Worldly Tutor
8. Summoner's Pact
9. Force of Vigor
10. Green Sun's Zenith with Dryad Arbor
11. Akroma's Memorial
12. Concordant Crossroads
