Start Deck 100 Battle Collection - Set Information

Set Overview

A Different Kind of Product

Before anything else: this is not a booster box. The Start Deck 100 Battle Collection is a fundamentally different product from everything else in the MEGA Series lineup, and understanding the format is essential before evaluating what's inside it. Each purchase gives you one random 60-card preconstructed deck drawn from a pool of 102 possible decks — 100 standard builds, one secret Deck #101, and one extremely rare variant of Deck #001. You don't know which deck you're getting until you open it. Think of it as a booster pack, except instead of pulling individual cards, you're pulling an entire playable deck.

Each deck contains 60 cards plus a damage counter and marker sheet. Every deck is guaranteed at least two Pokémon ex. The total card pool across all 102 decks exceeds 742 unique cards, with 57 cards being entirely new to the TCG. Released December 19, 2025, it sits between MEGA Dream ex and Nihil Zero on the calendar as a wildcard product with a collector profile all its own.

What's Inside

New Megas, New Characters, New Debuts

The new card highlights are significant. Mega Charizard Y ex makes its TCG debut here — separate from the Mega Charizard X in Inferno X, giving collectors both Mega Charizard forms across different products. The three Johto starter Megas all debut as well: Mega Meganium ex, Mega Emboar ex, and Mega Feraligatr ex, none of which had previously appeared in the TCG as Mega Evolutions. Pikachu ex and Lillie's Clefairy ex (illustrated by Naoki Saito) add further collector-grade new releases. From the Legends: Z-A cast, Karasuba appears as a new Supporter card alongside new Items PokéPad and Kai. Erika's Pokémon line and Larry's Pokémon line also feature among the new additions.

What makes these debuts particularly notable is exclusivity. Several of these cards — including the Johto starter Megas in their SR forms and the gold Mega Charizard Y ex MUR — exist only within this product. They aren't reprinted in standard booster sets. For collectors tracking the full MEGA era, the Start Deck 100 contains cards you simply cannot get anywhere else.

The Secret Decks

Deck #101 and the Gold Variant

The real collector intrigue lives in the secret decks. Deck #101 contains Super Rare versions of Mega Meganium ex, Mega Emboar ex, and Mega Feraligatr ex — the Johto starter Mega trio in premium form, only available through this specific pull. Based on community data from a 1,000-deck sample, Deck #101 appeared approximately 4 times — a pull rate of roughly 0.4%. The even rarer variant of Deck #001 contains a gold Mega Charizard Y ex MUR, and was not confirmed pulled within the same 1,000-deck sample. Its actual rarity remains unquantified.

That scarcity is reflected in market pricing. The gold Mega Charizard Y ex MUR has traded at levels that place it among the most valuable singles in the entire MEGA Series — a card whose rarity is genuinely extreme, not just marketed as such. Deck #101's Johto starter SRs carry significant premiums of their own, given that the trio can't be pulled from any other product.

What Collectors Should Know

The Cards That Matter

Lillie's Clefairy ex SAR (found in Deck #032) is the marquee single — Naoki Saito artwork commands what the community calls the "Saito Tax," a consistent pricing premium driven by the illustrator's collector following. Boss's Orders: Karasuba SAR (#760, found in Deck #095) spiked to approximately 40,000 JPY at launch, driven by both competitive utility and the character's popularity from Legends: Z-A. Pikachu ex (#764) and Eevee (#755) sit in the next tier — each carrying strong collector demand driven by character popularity and illustration quality. The Mega Feraligatr ex SR from secret Deck #101 and the gold Mega Charizard Y ex MUR from the Deck #001 variant sit at the extreme end of rarity and desirability.

This product appeals to a specific kind of collector — someone who appreciates the lottery mechanic, the debut Megas that don't appear anywhere else, and the thrill of potentially pulling a secret deck with cards unavailable in any other product. Every deck is playable out of the box with a guaranteed pair of Pokémon ex, so even the standard pulls have immediate utility. It's not for everyone, but for the right collector, it's one of the most interesting products in the MEGA era.
