Sprites by Starlight

You're on 6. Riven is on 7 and holds both battlefields: your Grand Plaza (A) with an Astral Heron (7), her Star Spring (B) with a Stellacorn Herder (3) and a Bedeviling Stranger (2). If she still holds one when her turn starts, she wins. Her runes are spent. At base: Lux, Illuminated (5; "When you play a spell that costs [5] or more, give me +3 Might this turn") and a Vanguard Sergeant you played this turn. In hand: Falling Comet (5: deal 6 to a unit at a battlefield), Sprite Burst (5: play two ready 3 Might Sprites with Temporary[Temporary]) and Moonlight Affliction (7). Five ready runes: one big spell. Take both.

• 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.
