Upgraded

• Cost: 2
• Effect: Deal 18 damage. Next turn, gain 3 energy.

A unique card that attacks now while boosting next turn's energy. You spend 2 energy this turn but get 2–3 extra energy next turn — effectively a 2-turn energy investment. 15–18 damage for 2 cost is standard on its own, but the next-turn energy boost is what makes it powerful.

Especially effective when you're planning to burn a lot of cards next turn. Hegemony → (next turn) big plays x2 is a brutal flow. Upgraded, the next-turn +3 energy is equivalent to casting two 2-cost cards for free.

• Play it the turn before you want to land a big card (Comet, Seven Stars, Knockout, etc.)
• The next-turn cost boost stacks, so stacking Hegemony multiple times lets you play even more next turn
• The upgraded +3 next-turn energy is extremely strong — upgrade priority is high

• Comet: 0-cost big hit that spends 5 stars. Hegemony's next-turn energy lets you play Comet and other things in the same turn
• Nullify: first card each turn is free. Combined with Hegemony's next-turn energy, it's monstrous
• Aggregate: retains your whole hand next turn and stacks costs and resources. Paired with Hegemony you can drop a huge batch of cards

• Regent High-Cost Orbit Build (B-tier)
• Regent Resource Explosion Build (A-tier)
