Quandrix, the Proof Cascade Shenanigans

3 Views
Article Index

Commander Overview

Quandrix, the Proof is the Simic dragon from Strixhaven, and he unlocks all kinds of fast shenanigans by giving your instants and sorcery spells cascade. I’ve seen some builds that use him as an Eldrazi commander or a classic green creature beatdown deck, capitalizing on top-deck manipulation spells like Brainstorm to rearrange your cascade hit.

I’ve built this deck as a bracket 4 deck, without the Eldrazi subtheme. Instead, we want to take extra turns to force a draw, or use some of the combos to make our opponents draw their whole libraries. This deck isn’t a cEDH deck (Quandrix is by far the best Simic option for that), but it can pop off easily and out of nowhere.

How to Play the Deck

Many of the combos required to win the deck don’t require Quandrix on the field. He’s more of a utility creature to cast if you have the mana. You can use him to hit big creatures like Nezahal, Primal Tide off cheap stuff like Treasure Cruise. Alternatively, casting 1-mana spells can help you find Ancestral Vision to draw cards.

The deck is built around not having Quandrix out for a while, since he is expensive to cast. There are a lot of 1-mana spells – countermagic, top-deck manipulation, removal – so don’t fret about hanging onto stuff to use Quandrix’s ability. Instead, play like you’re in a Simic slop pile, and use Quandrix’s ability to hit big stuff off Dig Through Time or something. It works best when he’s a tool, not the kingpin.

It can be tricky to know what you’re going to hit with Quandrix’s Cascade triggers, which is why this deck is fun. It can change the board-state in the blink of an eye, and with enough mana you can grab all kinds of cool stuff with cascade. It’s unpredictable, which puts it solidly in bracket 4, since it lacks the inevitability and consistency of a cEDH deck.

How We Win the Game

There are a bunch of ways we win the game, but one of the most efficient ways is to use Food Chain and Misthollow Griffin to give you infinite storm and hit your opponents with Brain Freeze

Prerequisites:

Infinite Storm and Mill

Combo Sequence
Cost1
1
1. Cast Misthollow Griffin if it’s not already on the battlefield.
2
2. Sacrifice Griffin to Food Chain, netting 5 blue mana
3
3. Recast Griffin and continue sacrificing it to Food Chain for infinite storm count
4
4. Cast Brain Freeze, milling your opponent’s whole libraries
5
5. Pass the turn.
×

This combo is weak to flash enablers like Borne Upon the Wind, since passing the turn gives each opponent the chance to do things in their upkeep, on other people’s turns, etc. If you’re playing in a blue-heavy pod and you suspect you might lose after passing, you can always mill yourself and use Thassa’s Oracle.

Another combo that will disrupt the board involves taking near-infinite turns and attempting to kill players through combat damage

Prerequisites:

Infinite Turns

Combo Sequence
Cost5
1
1. Cast Capture of Jingzhou and resolve it to take an extra turn.
2
2. Activate Isochron Scepter, copying Noxious Revival to put Capture of Jingzhou on top of your library.
3
3. Pass the turn to yourself, drawing Capture of Jingzhou.
4. Repeat from step 1
×

Once you have infinite turns, you can use any of your flying creatures to swing on your opponents each turn, eventually killing them. You could also just demonstrate the loop and hope they concede.

Other Combos

Outside of the combos I’ve listed above, there are a handful of others that can also win you the game, or at least get you close.

Combos:

Once you have infinite blue mana, you can use it to force everyone to draw their decks with Faerie Mastermind, protecting yourself from losing with Endurance. With infinite colorless mana, you can cast a massive Finale of Devastation and kill people with combat damage. With infinite untaps, you can use The One Ring to draw your deck and resolve a Thassa’s Oracle.

Strengths of the Deck

Insane amounts of card draw and lots of mana-makers

A lot of possibilities with the combos, they aren’t locked in place since many cards allow you to win the game.

Weaknesses of the Deck

Qunadrix is a gambler, and sometimes you hit dookie.

Instant-speed interaction from the table can make certain win-lines fail

Conclusion

Quandrix isn’t for those seeking consistency or reliability. Quandrix is best suited to a chaotic and whimsical playstyle. I think this deck is super funny, but it will falter sometimes. We’ve got solid ways to win the game, and if you are a skilled pilot who can piece those wins together, it will feel awesome. Sometimes, you just get RNG-baited and have a board of junk.
