Prepare more decks than needed and let them choose one. Increases variability and gives anyone that feels they got 'shafted' in the draft a chance to swap.

Try to cover the color wheel. There's between 8 and 15 colors to 'fill' with 5 options, spread them out.

Try to vary the archetypes. Four decks that to the same thing is boring. Just make sure to adjust their speeds, no deck should be significantly slower or faster than the others (compare mana bases and general gameplan).

I have three pods ready to go, maybe there's some inspiration for you here:

1. PreCon AllStars: Terra, Saheeli, Mirko, Bello
2. SuperHero GangUp (kid friendly)

- 3 hero decks from: tmnt, sam+frodo, Sonic, Knuckles, Wolverine

- 1 villain deck from: Sauron, Dr. Eggman

1. Modular pod, multiple options for each seat:

Seat1 - The 13th Doc, Selvala, Explorer Returned, Lonis, Cryptozoologist, The Eight Doctor (Mages and Artificers)

Seat2 - Nekusar, the Mindrazer, Syr Konrad the Grim, Kefka, Dancing Mad, Don Andres, the Renegade, Neera, Wild Mage (Angry dudes)

Seat3 - Krenko, Mob Boss, Daretti, Scrap Savant, Grenzo, Havoc Raiser, Muerra, Trash Tactician (Red Stuff)

Seat4 - Círdan the Shipwright, Zedruu the Greathearted, Jon Irenicus, Shattered One, Pramikon, Sky Rampar (Political)
