One of the biggest metagame surprises was the unexpected resurgence of Insidious Roots decks. Five members of team Handshake Moxfield—Simon Nielsen, Matti Kuisma, Eli Kassis, Julien Henry, and Alex Friedrichsen—locked in a Golgari build that they hoped would catch the competition off guard.

"The deck does crazy powerful things when Insidious Roots is involved and has a lot of staying power through Tyvar, Jubilant Brawler and Overlord of the Balemurk," Simon Nielsen explained. The Pro Tour champion was clearly intrigued: "It was hard to determine in testing whether this deck was great or just ok, and I was very curious to see how this would do into an unsuspecting field."

The key card in the deck is Insidious Roots, an enchantment capable of flooding the board with Plant tokens. Every time you exile a creature card from your graveyard with Molt Tender or Scavenging Ooze, or return one with Overlord of the Balemurk, Insidious Roots creates a Plant, then buffs all of your Plants with +1/+1 counters. Tyvar, Jubilant Brawler amplifies this synergy even further by letting your freshly sprouted Plants tap for mana immediately, fueling truly explosive turns.

The deck picked up several upgrades from recent sets, including Dark Confidant for the sideboard and Dragon Sniper as a cheap creature with deathtouch. But the real standout addition is Town Greeter, which fills the graveyard and generates card advantage. All of these new additions provide fuel for Molt Tender while maintaining a sufficient density of creatures for Tyvar's second loyalty ability.

Haywire Mite also fits in for similar reasons, and it offers valuable utility against Cori-Steel Cutter, Temporary Lockdown, and Omniscience in a metagame teeming with targets. All in all, even though the archetype has largely flown under the radar, it quietly posted strong results at the recent Regional Championships. And now, under the bright lights of the Pro Tour, all eyes will be on whether it can rise to the occasion.
