Second concept of a double Forensic Researcher infinite-untap combo deck.
Still trying to pay off with Unctus, Grand Metatect to draw/discard the deck. And Deeproot Pilgrimage to make infinite tokens.
Invasion of Segovia
allows the many tokens to Convoke the noncreature spells like Repulsive Mutation or Outrageous Robbery. (Maybe I should try a Doppelgang, but with infinite convoke it'll break Arena.)
To try to get the battle flipped, we're trying to push through evasive attackers like Tempest Hart or Elusive Otter. Lost in the Maze can clear out blockers and can also hexproof the attackers.
Inga and Esika effectively gives Convoke for creature spells. And giving all your creatures the tap-for-mana ability synergizes with Lost in the Maze to guard against all targeted removal or shenanigans.
This also helps get big Ingenious Prodigy casts. Getting an extra card for a few turns and then having a convoke body left over isn't bad, but with Inga you can go bigger.
Alquist isn't directly in the deck but Alquist Proft's Eidetic Memory is. Nearly all the creatures give bonus value when you put counters on them. Unctus with double Researcher or convoke bodies cause lots of extra draws that Memory turns into lots of counters. The Prodigy might lose a counter on upkeep but can get it back at attack time thanks to the Memory.
Living Conundrum gives you a safety net so you don't have to worry when churning a lot of draw/discards.
Likeness Looter helps with drawing more cards or recreating combo pieces that got killed or milled. Lier, Disciple of the Drowned can flashback the adventures or the X instants from the grave.
A few extra slots I'm filling out with some test cards. The Reality Chip can be a convoke body but when Reconfigured helps you plan out your topdecks vs Unctus. Titania, Voice of Gaea
/ Argoth, Sanctum of Nature
combo is mainly to see if the life gain possibility has any value. All-Seeing Arbiter might be able to neutralize some threats while you're in draw/discard mode.
