The Ur-Dragon · maximum Bracket 4

Command
the whole sky.

Put the sovereign into combat. Multiply the attack trigger. Turn one connection into a hand full of Dragons, a battlefield full of permanents, and another combat waiting behind it.

The sovereign sequence

Four beats.
Then the horizon moves.

This list is not conventional Dragon battlecruiser. Its early turns create colored mana and tutor access; its decisive turn puts The Ur-Dragon into combat with protection and turns the trigger into the next engine.

01

Build five colors

Fetch typed duals, cast land ramp, and keep a hand that can make green early. Eminence turns Scaled Nurturer into a one-mana Dragon dork.

02

Open the command gate

Hard-cast the commander—or Entomb Hellkite Courser and reanimate it before combat to put The Ur-Dragon onto the battlefield with haste.

03

Declare the sky

Attack with as many actual Dragons as it is safe to declare. Every Ur-Dragon source draws that many cards and may place one permanent.

04

Drop the next age

Land Dracogenesis for free Dragons, Call the Spirit Dragons for indestructibility, or an extra-combat piece that converts the first attack into the last turn.

Opening hand doctrine

Two to four lands, early green, and one accelerator is the floor. A tutor or cheap protection upgrades the keep; two giant Dragons without launch infrastructure do not.

Attack-trigger command deck

How many skies answer?

Count only Dragons declared as attackers. Myriad tokens enter attacking later and do not increase this number. Each Ur-Dragon copy supplies its own trigger; Roaming Throne naming Dragon doubles each other Dragon's trigger.

Exact ruleOne permanent may enter for every resolved Ur-Dragon trigger.

One Ur-Dragon trigger sees four declared Dragons.

Myriad flight lab

Copies for every horizon.
Triggers only where earned.

Myriad is devastating here because the best hosts reward entering or connecting. It is not an Ur-Dragon trigger multiplier by itself, and legendary copies need Sakashima's legend-rule shield.

They enter attacking

That bypasses attack declarations. No new Ur-Dragon, Atarka, Desert Were-Worm, or other “attacks” trigger is created.

They do enter

Dragon Tempest, Terror of the Peaks, Aura Shards, and an Astral Dragon copy's own enter ability still see a battlefield event.

They can connect

Ancient Dragon and Balefire damage triggers work normally if the individual copy deals combat damage to its defending player.

Legends collide

Legendary Myriad copies are normally put into the graveyard before damage. Auton Soldier's copied nonlegendary exception survives.

Battlefield breach routes

Pay less.
Arrive larger.

The strongest turns do not pay retail for a queue of seven- and eight-mana Dragons. Choose a route, protect the first hinge, and know which effects require a spell to be cast.

Closing protocols

One connection.
Then again. Then forever.

Two deterministic repeat-combat packages coexist with finite extra combats and commander damage. The table should know these lines are intentional before the game begins.

Repeat combat A

Savage Ventmaw + Aggravated Assault

  1. Attack with Ventmaw.
  2. Add six mana.
  3. Spend five after combat on Assault.
  4. Untap, attack again, repeat.
Deterministic once Ventmaw can attack.
Repeat combat B

Sword of Feast and Famine + Aggravated Assault

  1. Connect with the equipped creature.
  2. Untap all lands.
  3. Produce five mana after combat.
  4. Activate Assault and repeat.
Needs a connection and five land mana.
Commander kill

The Ur-Dragon + Jeska

  1. Cast the commander from the command zone at least once.
  2. Use Jeska's 0 on The Ur-Dragon.
  3. Connect for 30 commander damage.
Courser alone does not add Jeska loyalty.
Finite burst

Desert Were-Worm

  1. Attack with total power 12 or greater.
  2. Untap the attackers.
  3. Take one additional combat.
“First time each turn” prevents a loop.
Klauth is not Assault mana.

Klauth's mana can only cast spells. It cannot pay Aggravated Assault's activated ability, even though it persists across steps and phases.

Opening seven simulator

Keep the runway.
Mulligan the parade float.

A sample is a teaching aid, not a probability model. The verdict checks lands, early acceleration, color access proxies, and whether the hand contains only expensive spectacle.

Deal a hand to begin.
