How to build a Gen 1 Pokédex binder that actually finishes

Kanto is the binder most returning collectors start with, and for good reason. 151 slots is small enough to picture finishing, and every single Pokémon in it has been reprinted until the printing press gave up.

This is the plan for actually closing the binder instead of getting to slot 130 and stalling. If you're building from scratch, the whole thing is reachable in 12-18 months at a reasonable pace.

Why Kanto is the easiest 151 to close#

Every Pokémon from Bulbasaur to Mew has had at least a dozen English printings since 1999. Most have had dozens more. The Charizard slot is spoiled for choice. Even the forgotten slots (Farfetch'd, Mr. Mime, Jynx) have modern printings you can actually find.

Compare this to any other generation. Unova only got a full-set reprint treatment once. Sinnoh rarely gets dedicated sets. Kanto gets one nearly every year because the corporate side of Pokémon understands exactly where its nostalgia cash comes from.

The other structural advantage: WOTC-era originals exist for every Gen 1 Pokémon, and they're priced for collectors, not investors. A Jungle-era Jolteon or Venusaur holo stays affordable, usually a few dozen dollars raw. You can build a partial-WOTC Gen 1 binder without mortgaging anything.

Picking your face-card tier before you start#

The biggest mistake on a Gen 1 build is not deciding up front what "filling a slot" means. Three tiers are worth considering.

Budget tier#

Base rare or reverse holo for every slot. Average cost per slot: $1-3. Total build cost: roughly $200-400 depending on how patient you are with singles pricing.

Best for: first binder, kids, anyone who wants to finish quickly and upgrade faces over time.

Mid tier#

One modern holo or ex card per slot. Average cost per slot: $3-8. Total build cost: roughly $500-1,000.

Best for: most collectors. Gives you visible variety on the binder page without the chase-card premium.

Show tier#

IR or SIR for the headliners (Charizard, Mewtwo, the starter trio, legendary birds), modern holos for the rest. Average cost per slot: $5-15, with some slots blowing past that. Total build cost: $1,500-3,500, with the Charizard slot alone capable of pushing it higher.

Best for: long-term collectors who want a binder that can sit on a card show table.

The tier you pick is not permanent. Most collectors start budget, then upgrade face cards one at a time over the years. That's the correct move, not a compromise.

The 15 slots that trip everyone up#

Most of the 151 is easy. These are not.

The legendary trio: Articuno, Zapdos, Moltres#

Articuno (144), Zapdos (145), and Moltres (146) all have strong modern IR and SIR printings across Pokémon 151 and earlier sets. Budget-tier alternatives exist (reverse holos or older base holos), but many collectors treat the three legendary birds as one of their first "save up for the upgrade" targets.

Mew and Mewtwo#

Mew (151) and Mewtwo (150) are the two slots that won't cheapen. Mew ex has a Special Illustration Rare in Pokémon 151 (193/165) that sits well into three figures raw. Mewtwo's modern options include Pokémon GO era alt arts and Celebrations promos, all premium.

Farfetch'd, Mr. Mime, Jynx, Lickitung#

The cultural afterthoughts. These slots have maybe three or four modern printings each, and because nobody chases them, the ones that exist tend to stay in stock on singles sites at low prices. Good news for budget builds, slight frustration for anyone trying to find a premium face card.

Ditto#

Ditto (132) is sparser than it should be in modern print runs. The Pokémon GO set gave Ditto a clever "disguised as another Pokémon" treatment, which is the face card worth hunting.

Electabuzz, Magmar, Pinsir, Scyther#

Mid-tier pulls with solid art across eras but rarely headline cards. Easy to fill, easy to upgrade later.

The three sets that carry a 151 binder#

If you bought nothing but these three sets, you'd fill most of the binder.

Pokémon 151 (sv3.5)#

Released 2023. 165 numbered cards covering every Kanto Pokémon plus alt arts. This is the set. A six-pack booster bundle runs around $150-200 at retail these days, with sealed boxes well north of that. One bundle fills six packs worth of slots, which is enough to cover most commons and give you a shot at one of the chase cards.

Three IRs and SIRs worth naming specifically:

• Charizard ex SIR 199/165
• Blastoise ex SIR 200/165
• Venusaur ex SIR 198/165

The Kanto starter trio in SIR form is the most satisfying three-card pull in modern Pokémon TCG, full stop. See the Pokémon 151 set page for the full list.

Evolving Skies#

Released 2021. Known for Eeveelution alt arts, but also home to Dragonite VMAX alt art and a few other Kanto slots that landed perfectly. If you're also building an Eevee binder, you're opening this set anyway. The Kanto-slot benefit is a nice side effect.

Celebrations#

Released 2021 as the 25th anniversary set. Short print run, but almost every card is a Kanto slot with premium treatment. Charizard reprints, Pikachu reprints, Mew reprints. Expensive per card but punches above its card count.

Pacing the build so you don't burn out#

The reason most 151 builds stall at slot 130 is pace. You buy faster than you enjoy, then you stop because the remaining slots feel like a chore.

One pace that works for most collectors: one gym-leader team per month.

Work through the original Red/Blue gym leaders in order. Brock first: Geodude, Onix, Zubat line. Then Misty: Staryu, Starmie, Psyduck, Goldeen. Then Lt. Surge: Pikachu, Voltorb, Magnemite. And so on through Giovanni.

Each month you're closing 6-12 slots with a thematic constraint that makes the buying decisions for you. You finish the eight gym teams in eight months, then spend four months on the Elite Four and wild-area gaps.

This pace costs $30-80 per month at mid tier, hits eighteen months to finish, and avoids the spreadsheet fatigue of dumping $500 on singles in one night.

Using the app to track what's left#

The generation filter on the binder shows all 151 Gen 1 slots on one page. Green for filled, grey for empty. It's the fastest way to see where the holes are, and it's the view that makes the "oh I'm closer than I thought" realization happen around month four.

How DexBindr organizes your collection covers the slot model in detail. For the Gen 1 build, the two features that matter most are:

1. Generation filter (shows you just the Kanto view)
2. Cost basis per slot (so you know what you actually spent when the binder closes)

Browse every card in the database for free. Your first ten slots are free. Unlimited slots and cross-device sync are on the paid tier.

When to buy singles vs chase booster packs#

The short answer: buy singles for slots you know you want and don't have. Buy packs for the handful of sets where the act of pulling is the entertainment.

Pokémon 151 is worth opening in pack form because the set itself is fun. Obsidian Flames is worth opening if you like the Charizard chase. Everything else, once you're past slot 80 or so, is more efficient as singles.

The singles-vs-packs math only works against you when the binder is already 80% full. In the early months, pack opening is the reward that keeps the project going.

The finishing note#

A Gen 1 binder that closes is the foundation for everything else. Most collectors who finish Kanto keep going, either into Johto (Gen 2 is reachable, the pool is smaller) or into theme builds like Eevee lines or the Charizard retrospective. A few stop at 151 and treat it as the collection, which is also a valid answer.

If you want to see your Gen 1 progress laid out as a single page, the generation filter in the app is the view for it. Start wherever your shoebox ends.
