Assault the Heron

You're on 7 and held A this turn (your Kinkou Monk is there): conquer B for your 8th. Riven is on 7 and holds B (Star Spring) with an Astral Heron wearing Blade of the Exile: a 10. If she still holds B when her turn starts, she wins. Her runes all went on the Blade. You played Jayce, Hammer in Hand (5) this turn, so he's exhausted at base: "When I become ready, choose one to give me this turn — Assault 2[Assault 2] / Deflect 2[Deflect 2] / Ganking[Ganking]". Beside him, Tools of Empire is ready (Empower[Empower] [2]; Exhaust[T]: a unit +2 Might this turn, +4 if it's Empowered). You hold Acceleration Gate (3 Energy + [C]: ready up to 4 units, gear and/or runes), Stupefy and a Mountain Drake, with three runes ready. Defender of Tomorrow is spent. 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 Hallowed Tomb (A) this turn — it stays Scored, whoever is there now. Conquering Star Spring (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.
