Runes

Cards cost resources, and runes make them. The number in a card's top-left corner is its Energy; the rune icon under it, like [Fury], is its Power. Together they are the cost. You bring a separate Rune Deck of 12 runes. Each turn you channel 2 of them: you put them from your Rune Deck onto the board, ready to use.

• Energy is the number in a card's top corner. Tap (exhaust) a rune to add 1 Energy. Energy has no colour, so any rune will do.
• Power is the coloured cost below it, like 1 Fury. Recycle a rune to add 1 Power of that rune's Domain. The rune leaves the board and goes to the bottom of your Rune Deck, so you will channel it again later.
• One rune can do both: tap it for Energy first, then recycle it for Power.
• Card text shows Power as each Domain's rune symbol: [Fury] Fury, [Calm] Calm, [Mind] Mind, [Body] Body, [Chaos] Chaos, [Order] Order. A rainbow [C] is Power of any Domain, and a number like [2] is Energy.

What you add goes into your Rune Pool until you spend it. The pool empties at the start of each Main Phase and at the end of each turn, so spend it while it lasts. On the table you don't have to tap anything yourself: play the card and the runes pay for it.

One rune gives at most 1 Energy and 1 Power, so 6 runes pay at most 6 Energy and 6 Power. A recycled rune leaves the board, so tap runes freely but recycle only when you need the Power.

• 
  A Fury Rune. Tap it for 1 Energy, or recycle it for 1 Fury Power.
• 
  Hextech Ray costs 1 Energy and 1 Fury Power.

Some cards also carry keywords in brackets, like Action[Action], Assault[Assault] or Ganking[Ganking]. Each one is short for a rule that a later lesson explains. None of them matters in this drill.
