Energy recharges over time; every card costs energy and your hand of four cycles as you play.
Pilots are cheap pressure; the 🚀 Mech Hunter deals triple damage to mechs.
Mechs drop from orbit with a landing shockwave, huge armor, expensive.
Spells: ✈ Airstrike bombs a lane, 🌀 Shock stuns it, 🔧 Repair heals your units there.
Fair play: the enemy earns energy at exactly your rate on every difficulty; higher difficulties only act faster and smarter. Watch the countdown by your energy bar.
Overtime: if nobody falls by 0:00, sudden death chips both bases until one breaks.
