How do you build combos between dragons in Game of Thrones: Dragonfire?

The heart of this game is synergy: one dragon applies an effect, another doubles its damage on it. A few locked-in combos:

• First-Strike → Caraxes: its fire goes from +100% to +150% when the target has First-Strike. And Syrax is exactly who hands out First-Strike.
• Panic → Shadowsong / Seasmoke: fire or physical damage ×1.5 on a panicking target.
• Control → Rhysarion: +30% fire instead of +20% on a controlled target. Land a Stun (Crimson) first.
• Vulnerable → Solstryker: tactical damage doubled on a Vulnerable target. Antares is the one who applies Vulnerable.
• Bleed → Arrax: its Weakened goes from 25% to 50% if the target is bleeding.

Build an army where one sets it up and another cashes it in. That beats three isolated bruisers every time.
