Primer
Welcome to my Lila primer, I've read through every legal common in the game right now and have constructed the deck as it is right now. You might want to swap out cards in the considering section to better fit your playstle/pod.

First of all you should always ask if your pod is okay with you playing Lila, Hospitality Hostess as she is acorn after all.

The goal of the deck:

Slam Lila, Hospitality Hostess down turn 3
Storm spells from the top of your deck to find your winning combo's
The winning combos's of the deck are from easiest to hardest:

Midnight Guard + Presence of Gond = Infinite 1/1 Elf Warrior tokens.
Devoted Druid + Ivy Lane Denizen/Sigil of the Nayan Gods + Presence of Gond = Infinite 1/1 Elf Warrior tokens (If you have both Ivy Lane Denizen and Sigil of the Nayan Gods you also have infinite green mana.
Pili-Pala + Ashnod's Altar + Presence of Gond = Infinite mana of any color, Infinite 1/1 Elf Warrior tokens.
These combo's require you to have Midnight Guard/Devoted Druid/Pili-Pala in play without summoning sickness. This is where our imposter in the form of Concordant Crossroads comes into play. This effectively can turn our combo's into instant wins. Alternativelty Crashing Drawbridge without summoning sickness can give haste as well.
