How to Play Uugguu, the Omniplasm in Commander

Bracket 3 · Our Uugguu decklist · Ooze Tribal

Our Uugguu list is Sultai Oozes and clones. Whenever another nontoken Ooze you control dies, Uugguu creates two 2/2 token copies of it, so every Ooze death doubles its value.

The deck makes every creature an Ooze with Arcane Adaptation, Maskwood Nexus and March of the World Ooze, copies its best creatures with Clone and Phyrexian Metamorph, and sacrifices with Ashnod's Altar and Birthing Pod to multiply them.

01The Commander

Uugguu, the Omniplasm is a three-mana 2/2 Ooze. Whenever another nontoken Ooze creature you control dies, create two tokens that are copies of that creature, except they're 2/2 and not legendary.

The copies keep enter-the-battlefield abilities. Acidic Slime dying makes two more Acidic Slimes, destroying two more permanents.

Making every creature an Ooze is the key. With Arcane Adaptation, Leyline of Transformation or Maskwood Nexus, any nontoken creature that dies becomes two.

02How This Deck Wins

  1. 1

    Make everything an Ooze

    Arcane Adaptation, Leyline of Transformation, Maskwood Nexus and March of the World Ooze turn every creature into an Ooze.

  2. 2

    Sacrifice for copies

    Ashnod's Altar, Phyrexian Altar, Birthing Pod and Prime Speaker Vannifar sacrifice creatures. Each one returns as two token copies.

  3. 3

    Double and overwhelm

    Doubling Season and Parallel Lives turn two copies into four. Biogenic Ooze and Biowaste Blob grow the swarm.

10How to Play

Opening hand

Keep hands with three lands, a ramp piece and a type changer or sacrifice outlet. Uugguu on turn three is ideal.

1

Early gameturns 1-3

Ramp and cast Uugguu. Play Arcane Adaptation or Leyline of Transformation early.

2

Mid gameturns 4-7

Play value creatures and clones, then sacrifice them for two copies each with Ashnod's Altar.

3

Late gameturn 8+

Double with Doubling Season, make everything 6/6 with March of the World Ooze, and swing.

Tips

  • Uugguu only copies nontoken Oozes, so the copies don't copy again.
  • Clones are nontoken, so they trigger Uugguu when they die.
  • Saw in Half on your own creature makes four tokens with Uugguu.
  • Token copies aren't legendary, so legendary creatures can have several copies.

Common mistakes

  • Sacrificing tokens to Uugguu's engine, which don't trigger it.
  • Losing Uugguu with no type changer backup.
  • Overextending into an exile wipe.
  • Forgetting the copies are 2/2.

Watch out for

  • Exile removal and graveyard hate.
  • Removal on Uugguu.
  • Effects that stop tokens.
  • Board wipes that exile.
