The 2 combo pieces

What must be in place

An opponent has at least seven cards in hand.

How to execute it

  1. If Rousing Refrain is in your hand, cast it by paying {3}{R}{R}.
  2. Otherwise, activate The Tenth Doctor by paying {7}, causing you to time travel three times, removing all time counters from Rousing Refrain and cast Rousing Refrain from exile without paying its mana cost.
  3. Resolve Rousing Refrain, adding at least seven {R}, and exiling Rousing Refrain with three time counters on it.
  4. Repeat from step 2.
  5. If an opponent has eight or more cards in hand, this combo nets infinite red mana.
