Meet Your Commander: Killian, Decisive Mentor
The Silverquill Influence precon from Secrets of Strixhaven delivers the most political commander in the set. Killian, Decisive Mentor is a 3-mana white/black commander that turns every enchantment into a control tool and every attack into card advantage.
His two abilities create a complete political engine:
- Board Control: Whenever an enchantment you control enters, tap up to one target creature and goad it. Every Aura you play forces an opponent's creature to attack someone who isn't you.
- Card Advantage: Whenever one or more creatures enchanted by your Auras attack, draw a card. Your goaded creatures attacking their owners' opponents draws you cards.
The genius of Killian is that both abilities work together: you play Auras on opponents' creatures to goad them (ability 1), and when those goaded creatures attack (they have to!), you draw cards (ability 2). Your opponents fight each other while you profit.
Key Synergies: How the Deck Works
Political Warfare
Goad forces creatures to attack someone other than you. By enchanting opponents' creatures with your Auras, you control who fights whom. Meanwhile, Killian's second ability draws you a card every time those enchanted creatures attack — which they must. You sit back and draw cards while your opponents tear each other apart.
Recursive Auras
The real power comes from Auras that return when the enchanted creature dies. Cards like Ghoulish Impetus and Eye of Nidhogg come back after the goaded creature dies in combat, letting you retarget them to a new creature — triggering Killian's goad again. It's an infinite control loop.
The Voltron Backup Plan
If politics fails, suit up Killian himself with Ethereal Armor and All That Glitters. In a deck full of enchantments, these give him +8/+8 or more, threatening lethal commander damage in two swings.
Best Upgrades: Aura Synergies
Light-Paws, Emperor's Voice turns every Aura you cast into a chain reaction. When you cast an Aura, Light-Paws lets you search your library for another Aura with equal or lesser mana value and put it directly onto the battlefield. Each Aura entering triggers Killian's goad — so one Aura cast can tap and goad two creatures. Explosive value for $1.17.
Ethereal Armor is the ultimate voltron Aura. For just {W}, it gives +1/+1 for each enchantment you control plus first strike. In a deck with 6-8 enchantments on the field, that's easily +7/+7 with first strike. Put it on Killian and threaten lethal commander damage while also triggering his goad on entry.
All That Glitters is similar but counts artifacts too (Sol Ring, Arcane Signet, etc.). With 8+ enchantments and artifacts in mid-game, this is +8/+8 or more for just 2 mana. Between this and Ethereal Armor, Killian becomes a one-shot commander damage threat.
Best Upgrades: Goad & Political Tools
These Auras are the deck's engine pieces — they goad permanently and come back when the creature dies, creating an endless loop of political control.
Ghoulish Impetus is the best goad Aura for Killian. It permanently goads the enchanted creature and gives it deathtouch, ensuring it trades in combat. When the creature dies, Ghoulish Impetus returns to the battlefield at the next end step — triggering Killian's goad on a new target. It's a recursive removal and goad engine that never stops.
Eye of Nidhogg transforms an opponent's creature into a 4/2 flying deathtouch Dragon that's permanently goaded. It's virtually guaranteed to trade in combat, and when it does, Eye returns to your hand — ready to be cast again on a new target, triggering Killian again. Incredible recursive value at just 36 cents.
Nurgle's Rot is a {B} Aura that enchants an opponent's creature. When that creature dies, you get the Aura back AND a 1/3 Demon token. At just one mana, you can cast it the same turn as Killian to immediately trigger his goad. The Demon token provides a blocker while you set up more political plays.
Best Upgrades: Removal & Control
Winds of Rath is this deck's secret weapon. It destroys all creatures that aren't enchanted. Your Aura-wearing creatures survive while everything else dies. In a deck built around enchanting creatures, this is a one-sided board wipe for just 5 mana and 38 cents. It's the most impactful budget card in the entire list.
Sphere of Safety is the ultimate pillow fort. Creatures can't attack you unless their controller pays {X} per creature, where X is the number of enchantments you control. With 5+ enchantments on the field, opponents effectively cannot attack you. Combined with Killian's goad forcing creatures to attack OTHER players, you become untouchable.
Best Upgrades: Card Advantage
Sram, Senior Edificer draws a card whenever you cast an Aura. Combined with Killian's draw on attack, you have a double draw engine: one card when you cast the Aura, another when the enchanted creature attacks. Your hand stays full while you control the board.
Hateful Eidolon covers the death side of the Aura lifecycle. When an enchanted creature dies, draw a card for each Aura you had on it. Killian draws on attack, Hateful Eidolon draws on death — together they cover every phase of the Aura strategy. At 17 cents with lifelink, it's an auto-include.
Best Upgrades: Finishers
Eriette of the Charmed Apple is the #1 synergy card for Killian. She prevents any Aura-enchanted creature from attacking you (redundant protection with goad) and at your end step, each opponent loses X life where X = number of Auras you control. With 5 Auras out, that's 15 damage per turn cycle across the table — you win without ever needing to attack.
Mantle of the Ancients is the ultimate recovery tool. It returns ALL Auras from your graveyard to the battlefield attached to one creature, each one triggering Killian's tap-and-goad. If you have 5 Auras in the graveyard, that's 5 creatures tapped and goaded, plus the enchanted creature gets +6/+6 or more. It turns a losing position into a game-ending turn.
Budget Breakdown
- Under $1: Ethereal Armor ($0.34), All That Glitters ($0.53), Eye of Nidhogg ($0.36), Winds of Rath ($0.38), Hateful Eidolon ($0.17) — Total: ~$1.78
- $1-5: Light-Paws ($1.17), Sphere of Safety ($2.77), Sram ($3.28), Mantle of the Ancients ($3.73) — Total: ~$10.95
- Premium: Eriette ($6.45), Ghoulish Impetus ($8.03), Nurgle's Rot ($8.78) — Total: ~$23.26
This is the most budget-friendly deck to upgrade in the entire Strixhaven set. You can make 9 impactful upgrades for about $13 by skipping the three premium cards. The core Aura strategy with recursive goad and card draw works beautifully on a shoestring budget.
Final Thoughts
Killian, Decisive Mentor is the puppet master of the Commander table. While other decks build boards and swing for damage, you sit back behind Sphere of Safety, goad opponents' creatures into each other, draw cards from the chaos, and drain everyone with Eriette's end-step trigger.
The deck wins through attrition and inevitability. Recursive Auras like Ghoulish Impetus and Eye of Nidhogg ensure you always have fresh goad targets. Winds of Rath keeps the board clean on your terms. And when the moment is right, Ethereal Armor and All That Glitters turn Killian into a voltron commander that kills in two swings.
This is Silverquill at its finest — words are weapons, and in this deck, enchantments are the ultimate form of persuasion.
