Quick Answer
To win solo with the 20 Strong Solar Sentinels Deck, focus on building a plasma engine early, then pivot to aggressive damage output before the Horde overwhelms your defenses.
Why Plasma Management Matters More in Solo
In solo play, you face the Horde alone. Every wasted plasma token is a turn closer to defeat. The Solar Sentinels deck rewards careful siphoning and spending, so you need a clear priority list from the start.
The Trade-Off: Speed vs. Stability
You can rush damage output early, but that leaves your plasma reserves thin for later waves. Alternatively, you can build a slow, stable economy—but the Horde doesn't wait. Find a middle ground: invest in one strong solar upgrade, then attack.
Solo Play Strategy Steps
- Step 1: Open with a Plasma Siphon: Play your cheapest plasma-siphoning card on turn one. This gives you the resource engine to afford bigger plays later. Common mistake: hoarding plasma instead of spending it on upgrades—spend early to scale. If you don't draw a siphon, discard and mulligan for one.
- Step 2: Build One Solar Tech Upgrade: Choose a single solar upgrade card (like a weapon or shield) and commit your plasma to it. Avoid splitting resources across multiple upgrades. Common mistake: trying to build two upgrades at once, leaving you with nothing fully powered. A single upgraded card often out-performs two half-built ones.
- Step 3: Clear the First Horde Wave Efficiently: Use your upgraded card to eliminate the first wave of moon bugs. Prioritize targets that deal damage to your plasma reserves. Common mistake: ignoring low-threat bugs—they can snowball if left unchecked. Focus fire on damage-dealers first, then clean up the rest.
- Step 4: Cycle Your Deck for Key Cards: After the first wave, use any draw or cycle effects to find your next solar upgrade or a high-damage attack. Common mistake: holding onto situational cards too long—discard them to dig for what you need. If a card doesn't help your current plan, cycle it.
- Step 5: Overwhelm the Final Horde Wave: When the final wave appears, unload all your plasma and upgraded abilities in one big turn. Common mistake: pacing your damage—go all-in because the Horde will not give you a second chance. Don't save resources for a future turn that may never come.
