Psychatog
Psychatog is the win condition. It’s a 1/2 for three mana, but the abilities are surprisingly powerful. For instance, attack with Psychatog then Gush returning two islands, discard all four cards then eat them from the graveyard and that’s +6/+6 right there (plus the gush, so +7/+7 if you had another card in your graveyard). It’s not hard to get to lethal in one swing with a Psychatog attack in this deck. You don’t commit to the attack until you’ve already won: you swing, the opponent has to decide whether to block, and then you pump in response. Wonder in the graveyard with an island in play gives Psychatog flying, making him much harder to block, and you can always dump Wonder to the Psychatog to get it in the ‘yard.
The deck spends the early game as a control deck, drawing cards and saying no, draw cards, counter spells, fill your graveyard, get your pieces together.
Duress can disrupt decks on turn one, or be saved to check if the way is clear to play a ’tog.
Intuition at instant speed can tutor three copies of Accumulated Knowledge, forcing the opponent to give you one — and then the other two are already in your graveyard, so the next copy draws three. But worth thinking through exiling any AKs from your graveyard unless you’re winning, since it just keeps getting better.
Build up the graveyard through normal draw spells, keep the opponent from resolving anything meaningful, and find a window where Psychatog can swing lethal through their defenses.

Sideboarding Thoughts
Engineered Plague: A single Plague naming Elf kills Llanowar Elves, Fyndhorn Elves, Quirion Ranger, Priest of Titania, and more simultaneously. Naming Goblin kills half the cards in their deck.
Hydroblast / Blue Elemental Blast: Destroys any red permanent or counters any red spell for one mana. Brings in against red-heavy decks where most of the threats are red.
Annul: Bring in against decks where key setup pieces are enchantments, like Sterling Grove, Opalescence, and Solitary Confinement, or that have annoying artifacts.
Zombie Infestation: Converts the excess cards from your cantrip engine into threats in matchups where you need to go a little wider.
Phyrexian Furnace: Chips away at graveyard-reliant strategies and can effectively cycle when you need it to.
Infest: Another board wiping card that kills most Elves and Goblins.
Deep Analysis: An extra copy of the main deck draw spell for matchups where you need additional card advantage and can afford to flashback from the graveyard later.
Haunting Echoes: Remove key pieces of your opponent’s strategy once one is in the bin.
