Elf deck that I'm building to bring to a casual environment. I might be playing this in multiplayer or 1v1. The sideboard is supposed to help deal with that (lots of help for flyers, repeatable lifegain to grind it out.)

Key Deck Interactions:

Wirewood Symbiote + any elf = escape to removal

Wirewood Symbiote + Elvish Visionary = REPEATABLE draw

Wirewood Symbiote + Elvish Archdruid + any elf = LOTS of mana

Wirewood Symbiote + Elvish Archdruid + Genesis Wave = WIN

Wirewood Symbiote + Wellwisher = LOTS of lifegain

Immaculate Magistrate + Joraga Warcaller = buffs for all elves

Immaculate Magistrate + Ambush Commander = LOTS of +1/+1 counters

Elvish Promenade + Immaculate Magistrate = LOTS of +1/+1 counters

Elvish Promenade + Jagged-Scar Archers = MASSIVE elf

Elvish Promenade + Elvish Archdruid = LOTS of mana

Quest for Renewal activates very quickly from the 8 mana elves. Allows for attacking with all creatures every turn because of pseudo-vigilance, using Immaculate Magistrate every turn for buffs, using Elvish Archdruid + Ezuri, Renegade Leader to regenerate or buff elves, activate Wellwisher every turn, or kill a flier every turn with Jagged-Scar Archers. It's a versatile card, but having only two prevents me from drawing doubles as it's a dead card once I already have one on the field.

Genesis Wave is a game-ender, barring a board-wipe(but that's probably negated by an Ezuri, Renegade Leader. There's only 4 non-permanents (2xElvish Promenade and 2xGenesis Wave) so little gets sent to the graveyard. Mana isn't an issue thanks to the interactions above that allow for adding large amounts of mana (normally around 10).
