Decklists:

Bill: Sliver Stax (https://tappedout.net/mtg-decks/thalia-hate-slivers/)
A spicy combo deck hidden beneath stax pieces and efficient sliver beats, this deck is looking to slow the game down and strike at the perfect moment.

Jan: Sydri, Life of the Party (https://tappedout.net/mtg-decks/sydri-life-of-the-party/)
In a format with so many cheap artifacts, a cheap and repeatable way to destroy them is aiming to give this deck the edge it needs to sneak through one of it’s combos.

Jim: Lazav, the Multifarious (http://tappedout.net/mtg-decks/29-01-19-suicidal-tendencies/)
A sleek 1.21 Average CMC is not the only thing that makes this deck stand out. Housing a suite of 0 mana 0/0 creatures, this tricky commander certainly lives up to his name.

Eliot: Xantcha Worldgorger (http://tappedout.net/mtg-decks/xantcha-worldgorger/)
A commander that you don’t want on your side of the battlefield and an easily disruptable all-in combo define this deck. Hold onto your butts, this is bound to be a wild ride.
