Urza, Lord High Artificer
Nim Deathmantle
Ashnod's Altar

Requires
Urza, Lord High Artificer must be on the battlefield. Nim Deathmantle must be on the battlefield. Ashnod's Altar must be on the battlefield.
Steps
  1. Activate Urza's second ability twice by tapping Nim Deathmantle and Ashnod's Altar, adding uu.
  2. Activate Ashnod's Altar by sacrificing Urza, adding cc.
  3. Nim Deathmantle triggers, causing you to pay 4 to return Urza from your graveyard to the battlefield and attach Nim Deathmantle to it.
  4. Urza enters the battlefield, creating a 0/0 Construct artifact creature token with "This creature gets +1/+1 for each artifact you control".
  5. Activate Urza's second ability by tapping the Construct, adding u.
  6. Activate Ashnod's Altar by sacrificing the Construct, adding cc.
  7. Repeat from step 2.
  8. Once you have infinite mana, you may repeat the loop while skipping step 6, resulting in infinite Construct tokens, and you may activate Urza's last ability any number of times.
Results
Infinite blue mana. Infinite colorless mana. Infinite creature tokens. Infinite death triggers. Infinite ETB. Infinite LTB. Infinitely large Construct tokens. Infinite sacrifice triggers. Play all cards in your library without paying their mana costs.
