commander · Yidris, Maelstrom Wielder
Entropic Uprising (C16).
A four-color chaos and cascade deck from Commander 2016, led by Yidris, Maelstrom Wielder — deal combat damage with Yidris to give every subsequent spell you cast cascade for the rest of the turn.
The Commander
Entropic Uprising is Commander 2016's chaos deck, and Yidris delivers one of the most explosive engines in the set. Whenever Yidris deals combat damage to a player, every nonland spell you cast for the rest of the turn gains cascade — meaning each spell you cast digs for a free additional spell. Hit with Yidris early in the turn and cast three or four spells and you've potentially played six or eight spells in one turn cycle. This deck rewards going wide on spells rather than building a traditional creature base.
Yidris, Maelstrom Wielder is a 5/4 trampler with cascade himself. He always digs for a free spell when cast. With Partner commanders available — Vial Smasher the Fierce for early pressure, Kydele or Thrasios for ramp — the deck supports multiple configurations depending on how aggressively you want to play.
Key Cards
Vial Smasher the Fierce
Vial Smasher deals damage equal to the mana cost of the first spell you cast each turn to a random opponent. In a deck casting seven- and eight-mana spells off cascade, that's a random hit for seven or eight damage every turn without attacking. Pair Vial Smasher with Yidris for a command zone that threatens opponents on both ends of the curve — Vial Smasher drains life while Yidris cascades through spells in combat.
Magus of the Will
Pay two mana, tap Magus of the Will, exile it, and cast any number of cards from your graveyard without paying their mana costs until end of turn. This is Yawgmoth's Will on a creature. After a cascade chain fills your graveyard with discarded cards, Magus of the Will converts that graveyard into a free second hand. Combined with Yidris giving cascade to all those spells, a single Magus activation can replay an entire game's worth of spells in one turn.
Goblin Spymaster
At the beginning of each opponent's end step, they must attack with at least one creature on their next turn. When every opponent is forced to attack, combat becomes chaotic. Players can't turtle up behind big blockers. Threats get neutralized by other opponents' attackers. Goblin Spymaster creates the political chaos this deck loves — opponents fight each other while you set up the Yidris cascade turn that ends the game.
Mindmoil
Whenever you cast a spell, put your hand on the bottom of your library and draw that many cards. In a turn where Yidris gives cascade to every spell, and cascade finds more spells, and Mindmoil replaces your hand with a fresh set of cards after each cast — you churn through a significant portion of your deck in a single turn cycle. Mindmoil finds answers, threats, and more cascade fodder whenever you're active.
Horde of Notions
A five-color 5/5 with haste, vigilance, and trample that lets you pay five mana to return any elemental from any graveyard to play. In a four-color deck, paying for WUBRG activations is feasible, and recurring key elementals from opponents' graveyards is a powerful late-game ability. Horde of Notions attacks for five with vigilance on the same turn it comes down, then can threaten recursion as early as the following turn.
How to Play
The key is getting Yidris through combat damage. Trample helps — a 5/4 trampler pushes damage through small blockers. Cast the highest-mana spells you can immediately after Yidris connects, as each cascade off those spells finds cheaper spells that can cascade further down the chain. Vial Smasher in the command zone punishes any spell you cast for seven or more. Pair Yidris with either Kydele for mana acceleration or Thrasios for late-game card filtering. The deck wins by finding one explosive turn — usually around turns six to eight — where Yidris connects, cascade chains resolve three or four times, and the board state becomes impossible to recover from.
