How to upgrade an Eternal Ascent trial deck
Upgrade a trial deck in three passes: cut the weakest one-of cards, raise your best attacker and best draw engine to full copies, then add booster singles that match the deck's existing colour pair. Keep the deck at exactly 50 main-deck cards and 10 Soul Cards at every step.

What should I cut first
Cut the single copies that do nothing on the turn you draw them — high-cost bodies with no immediate effect and situational answers to cards nobody in your store plays. Trial decks include those to demonstrate variety, not because they are strong.
Which cards should I add copies of
Identify the card that wins games when you draw it early and the card that refills your hand, then run the maximum legal copies of both. Consistency beats raw ceiling in a 50-card format because you see a smaller fraction of your deck per game.
Should I add a third colour
No, not while learning. Trial decks are built around a two-colour resource base; splashing a third colour costs you consistency far faster than it adds power. Add booster singles inside your existing pair first.
Which booster should I buy for singles
Buy from the set that shares your deck's colours and is currently legal — Booster Pack "Dawn of Palpagos" (EBP01) and Booster Pack "Legends Awaken", which the official products page dates to 30 October 2026, are the two obvious sources leading into Eternal Ascent's December release.
How do I keep the deck legal
Recount before every event: exactly 50 main-deck cards, exactly 10 Soul Cards, per-card copy limits respected, and every card in identical opaque sleeves. Deck Log, Bushiroad's official deck tool, enforces sizes for you and produces the list you register in Bushi Navi.
