Two Acts

You're on 6. Riven is on 7 and holds Star Spring (B) with Riven, Broken Blade (4) and a Stellacorn Herder (3) — if she still holds it when her turn starts, she wins. Her runes are spent. Forgotten Monument (A) is empty. Jhin, Murderous Artist (4, Ganking[Ganking]; "When I move, Add[Add] [1][C]") and Gemcraft Seer (3) are ready at base. In hand: Curtain Call (4; choose one: Draw 1 / Deal 2 to a unit at a battlefield / Deal 3 to a unit at a base / -4 Might to a unit at a battlefield this turn; Repeat[Repeat] for more) and Mega-Mech (7). Virtuoso has three spells banished: the fourth spell you spend 4 on channels runes and draws you a card. Three ready runes. Take both battlefields.

• 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.
