Dredge is best described as a midrange deck with combo elements. Against interactive decks Dredge generates card advantage with recursive threats, while interacting with the board thanks to Conflagrate. It is described as having combo elements because of the occasional fast draw it can generate when it finds its Prized Amalgams quickly. How powerful Dredge is at any given point is often related to how much graveyard hate people are playing. If you can dodge seeing cards like Rest in Peace and Leyline of the Void, this deck is very good. You can read more about Dredge on Star City Games here and here.
This is probably the deck I am most Internet famous for. I was paid a large sum of money to play this deck at an SCG open in an Owl Costume. It is a total hoot and if you enjoy sending your opponent’s cards back to their hand I would highly recommend this one.

This deck is capable of winning the game on the very first turn. It does so by putting Narset, Enlightened Master into play via Goryo’s Vengeance. Then we start taking extra combat steps with cards like Fury of the Horde. This is one of the few decks in Magic where you want to be sure you are choosing to draw. Not only do we want the extra card to try and kill with, but Gemstone Caverns is much better on the draw!
Narset, Enlightened Master
Emrakul, the Aeons Torn
Boseiju, Who Shelters All
Jeskai Ascendancy Combo, or JAC for short, is something that I can best describe as “interesting storm”. While it is a linear combo deck, the way we end up winning the game each time we play it is going to vary. Generally speaking we draw through our deck with cantrips and Jeskai Ascendancy loot triggers, while powering up our mana creatures to attack with. You can read my full primer about this deck on Gathering Magic here. You can also talk about this deck in the JAC discord server here.
