Power creep in trading cards, measured five ways
Power creep is the oldest argument in trading cards, and it is almost always made with one scary card. So we stopped arguing and measured it, five different ways, across Magic, Pokémon and Yu-Gi-Oh, using only numbers printed on the cards. Every single dimension inflated. But the surprise is that each game crept in a different currency.
The smallest creep. Magic barely grew raw bodies; the median 2-drop was below Grizzly Bears for two decades. But the share of pushed 2-drops still tripled.
Magic crept through TEXT and abilities, not raw stats. Where Yu-Gi-Oh piled on numbers, Magic piled on words.
Defense. Base Set topped out at a 120-HP Chansey; today a Mega Venusaur ex has 380.
Offense, and it tracks the HP curve almost exactly. Base Set Charizard hit for 100; a modern Charizard ex hits for 330. Attacks and HP tripled together, so games stayed the same length.
The single most inflated dimension we measured. Vanilla monsters went from 60% of new monsters to under 1%, and the effects that replaced them keep growing.
Each row is a full study; follow any card for its year-by-year method. Bars are the inflation multiple, smallest to largest.
Three games, three currencies
Lined up side by side, the studies say something no single one can. Power creep is real everywhere, but the games do not inflate the same way. Magic barely grew its raw creature bodies (1.3x) yet nearly tripled its rules text (2.6x): it adds power through abilities and words. Pokémon did the opposite, inflating raw numbers with offense and defense moving in lockstep (attack 3.3x, HP 3.2x), so a bigger hit meets a bigger wall and games stay the same length. Yu-Gi-Oh did both, and its card text (5.7x) is the most inflated single number in the whole comparison. The complaint “my game has power creep” is true in every case; what changes is the currency it is paid in.
FAQ
Is trading card power creep real?
Measurably, yes, in every game we checked. We took five independent measurements from printed card data across Magic, Pokémon and Yu-Gi-Oh, and every one inflated: Magic's creature stats (3 to 4 total stats, 1.3x), Magic's rules text (14 to 37 words, 2.6x), Pokémon HP (120 to 380, 3.2x), Pokémon attack damage (100 to 330, 3.3x), and Yu-Gi-Oh's card text (15 to 85 words, 5.7x). None of these use market prices; the numbers are printed on the cards.
Which game has the worst power creep?
It depends on what you measure, which is the whole point. Yu-Gi-Oh's card text is the single most inflated dimension we found (5.7x). Pokémon inflated its raw numbers hardest, with HP and attack damage both roughly tripling. Magic crept the least in raw creature bodies (1.3x) but nearly tripled in rules text. Every game got more powerful; they just did it in different currencies.
Did every game creep the same way?
No, and that is the most interesting finding. Magic added power through TEXT and abilities (rules text up 2.6x) while barely growing raw creature bodies (1.3x). Pokémon added power through raw NUMBERS, and its offense and defense inflated in lockstep (attack 3.3x, HP 3.2x), which is why games did not get shorter. Yu-Gi-Oh added power through both, and its text ballooned more than any other measure. Same phenomenon, three different design languages.
How was this measured?
Each row is the headline finding of a dedicated Foilio study, linked in the table, each built from an open card database (Scryfall, pokemontcg.io, YGOPRODeck) with no market data and outlier-immune medians or printed maxima. This page synthesizes them; follow any row to its full year-by-year method. Valued 2026-07-08.

The five studies
Magic: Creature body, total stats on a 2-mana creature
The smallest creep. Magic barely grew raw bodies; the median 2-drop was below Grizzly Bears for two decades. But the share of pushed 2-drops still tripled.
2.6xMagic: Rules text on a new card, median words
Magic crept through TEXT and abilities, not raw stats. Where Yu-Gi-Oh piled on numbers, Magic piled on words.
3.2xPokemon: HP ceiling, the hardest card to knock out
Defense. Base Set topped out at a 120-HP Chansey; today a Mega Venusaur ex has 380.
3.3xPokemon: Attack ceiling, the hardest single hit
Offense, and it tracks the HP curve almost exactly. Base Set Charizard hit for 100; a modern Charizard ex hits for 330. Attacks and HP tripled together, so games stayed the same length.
5.7xYu-Gi-Oh: Card text on a new card, median words
The single most inflated dimension we measured. Vanilla monsters went from 60% of new monsters to under 1%, and the effects that replaced them keep growing.
