Void Spark

You're on 7 points and Held A this turn. Your opponent (Rek'Sai, a Void deck) holds B with Rek'Sai, Breacher and Void Drone, both 3s. Kai'Sa, Survivor (4) is Ready at base; you hold Hextech Ray (1 Energy + 1 Fury) and one Mind rune. Your Legend, Daughter of the Void: "Exhaust[T]: Add[Add] [C]. Use only to play spells." Take B.

The Final Point: One point from victory, a Conquer gives you the final point only if you've Scored every battlefield this turn — by a Hold or a Conquer, either counts. Otherwise it draws a card instead. You've already Scored Void Gate (A) this turn — it stays Scored, whoever is there now. Conquering Sunken Temple (B) scores your final point.

• Move: drag ready units onto a battlefield (or click units, then click where they go). They wait there, faded, until you press Confirm in the panel on the right — units that fight together must move together.
• Runes: playing a card pays from them on its own. To float Energy or Power first, click a rune: Tap gives Energy, Recycle gives Power.
• Cards: drag a card from your hand onto its target, or click it and then click the glowing target. The play waits in the panel on the right until you confirm it (Esc cancels).
• Abilities:click your Legend (one click uses its ability), Gear, or a unit's ✧ badge.
• Point at any card to see it large; right-click to read it. Hint, Undo and Retry are at the top.
