The Hatsune Miku Secret Lair deck plays perfectly well straight out of the box, but like any precon, it wasn't tuned to maximize either commander's specific strengths. A handful of inexpensive swaps can meaningfully sharpen either build.
None of this is required to enjoy the deck, but if you're the type of player who likes tuning a precon, here's a reasonable starting point.
This guide focuses on budget-friendly additions, not a full competitive overhaul.
Small, targeted changes tend to work better than an all-at-once rebuild.
Additional token generators and lifegain payoff cards are the most efficient upgrade path for this build, since they directly amplify Trostani's core ability rather than working around it. Prioritizing cards that create multiple tokens at once over single-creature spells gets the most value per card added.
A handful of budget-friendly anthem effects or go-wide payoffs can noticeably raise this build's ceiling without a large investment.
Additional ramp spells and counter-synergy creatures amplify Vorinclex's doubling effect directly, letting the deck reach its bigger threats meaningfully earlier. Budget ramp spells are widely available and represent some of the most efficient upgrade dollars in the format generally.
Cards that place counters incrementally over several turns, rather than a single large burst, get more cumulative value from the doubling effect than one-time boosts.
An upgraded deck usually grows past its original 100-card footprint as you test additions. EVORETRO's Magnetic Card Deck Storage Box gives you room for the core deck plus a rotating pool of upgrade candidates.
Every new addition needs the same protection as the original cards. EVORETRO's Perfect Fit Sleeves keep new and original cards consistent.
The weakest cuts to make room for upgrades are usually the least efficient reprints that don't directly support either commander's core strategy, rather than removing cards essential to the deck's overall curve or mana base. Reviewing which non-foil reprints see the least actual impact in your own games is a good starting point.
Cutting conservatively, one or two cards at a time rather than a wholesale swap, makes it easier to evaluate whether each individual change actually improved the deck.
A reasonable upgrade budget for either build can meaningfully improve consistency without approaching the cost of a fully optimized competitive list. Setting a rough ceiling before shopping for additions keeps the project from creeping well beyond what the precon itself cost.
Spreading upgrades across a few purchases over time, rather than one large order, also gives you a chance to playtest each change before committing further.
Playing a few games with each new addition before deciding whether to keep it gives a much more reliable read than theorizing about a card's fit from the sleeve. Some cards that look strong on paper underperform in actual games, and vice versa.
Keeping a simple note of what worked and what didn't as you test changes makes future tuning decisions faster and more informed.
Community deckbuilding resources and Commander-specific strategy discussions focused on either Trostani or Vorinclex's typical archetypes are a more reliable source of upgrade ideas than generic best-cards lists not tailored to either commander specifically. Searching for discussion centered on the exact commander gives more relevant suggestions.
Cross-referencing a few different sources before committing to a purchase helps avoid upgrading based on a single, possibly outdated recommendation.
Joining a broader Commander strategy community, rather than relying only on card-specific searches, also surfaces general deckbuilding principles that apply well beyond just this one precon.
Over time, these broader principles tend to make future upgrade decisions faster and more confident, well beyond just this specific deck. That broader knowledge pays off across every future Commander project you take on.
No, it plays well straight out of the box.
Both are budget-friendly if you prioritize efficient, targeted additions.
Not necessarily, focusing on one build first makes testing easier.
Play several games with each change before deciding to keep it.
A few smart additions can meaningfully raise either build's ceiling without a big investment. Pick up EVORETRO's Perfect Fit Sleeves for every new card you add.
