Have You Ever Wanted to Attack Forever?

That's not a rhetorical question. In Commander, there's a very specific feeling that comes from declaring attackers, dealing damage, and then… doing it again. And again. And again. Bear Umbra plus Aggravated Assault gives you exactly that — and it does so for less than twenty euros in your pocket.

Let's break down how it works, where to run it, and above all how to keep it together when your opponents try to dismantle it.

The Mechanism, Piece by Piece

Let's start with the fundamentals, no rush.

Bear Umbra is an Aura that attaches to a creature. In addition to giving it +2/+2 and protection from destruction for your lands (the so-called totem armor), it does one precise thing: whenever the enchanted creature attacks, untap all your lands.

Aggravated Assault is an enchantment that, for three generic mana plus two red, lets you take an extra combat phase that turn — and you can activate it as many times as you can pay for it.

Put the two together and you get this loop:

1. You attack with the creature carrying Bear Umbra.
2. As soon as you declare attackers, your lands untap.
3. With those untapped lands you pay the Aggravated Assault ability: you get another combat phase.
4. You attack again → your lands untap again.
5. Repeat until your opponents are at zero.

The only technical requirement is having at least five lands (three generic + two red) available after the initial tap, or any combination of lands and mana rocks that lets you pay . With six or more lands on the battlefield, the loop becomes trivially infinite.

Color Identity: Who Can Run It?

Bear Umbra is green. Aggravated Assault is red. The combined identity is therefore Red/Green (Gruul), plus any commander that includes both of those colors.

Here are five commanders where this combo fits perfectly:

• Xenagos, God of Revels — the king of voltron aggro. He doubles the power of the attacking creature on your turn: with Bear Umbra attached on top, each attack puts up massive numbers from the very first combat.
• Ruric Thar, the Unbowed — forces opponents to play creatures or take six damage. Hard to remove, and an excellent Aura target.
• Jetmir, Nexus of Revels — the more creatures you have, the more bonuses you get. Every extra combat with your entire board is lethal in a hurry.
• Klauth, Unrivaled Ancient — generates enormous amounts of mana when it attacks. Often pays for Aggravated Assault all by itself on the first swing.
• Wulfgar of Icewind Dale — doubles "whenever this creature attacks" triggers: with him on the battlefield, Bear Umbra untaps your lands twice each combat. The loop becomes even more robust.

How to Protect It (and How Not to Lose It Stupidly)

The combo has two clear weak points: the target creature and the enchantment Aggravated Assault.

To protect the creature, you already have a built-in safety net thanks to Bear Umbra's totem armor: if someone destroys the creature, the Aura is destroyed in its place instead. Great insurance. Beyond that, Swiftfoot Boots and Lightning Greaves are your best friends — they provide hexproof or protection and cost very little.

For Aggravated Assault, the story is different: it's more exposed. Keep it in hand until you're ready to close out the game within a turn, or build a window with reactive spells like Veil of Summer or a simple Autumn's Veil to lock down the window in which you cast it.

The ideal moment to unleash the loop is when at least one opponent is low on life and the other two have burned through their instant-speed interaction. You don't need to kill everyone at once: you just need the table to be unable to stop you in that window.

Budget vs. Premium: How Much Do You Really Want to Spend?

The good news is that the heart of the combo costs very little: €12.26 for Aggravated Assault and €6.30 for Bear Umbra, for a total of €18.56. That's two cards, not a chain of expensive pieces.

In the budget version, you can rely on creatures already in your deck as the Aura's vehicle — any creature with evasion or one big enough to get through works fine. Boots and Greaves can be found for under two euros each.

In the premium version, invest in green tutors like Worldly Tutor or Chord of Calling to find the right creature, and in stack protection like Deflecting Swat to answer countermeasures for free.

The Verdict? This Combo Earns Its Spot

Bear Umbra plus Aggravated Assault is one of those packages that won't make you feel guilty: it's accessible, it explains itself in thirty seconds, and it works inside archetypes that already exist — aggro, voltron, go-wide. It doesn't require a commander built around it; it adapts to you.

Take this home with you: in Gruul, if you attack often and you have lands, this combo isn't an alternative win condition — it's the natural conclusion of what you're already doing.
