After several years of absence, the TCG is bringing back the “Mega Evolution” mechanic in full force. According to the official expansion overview, the set titled Mega Evolution is scheduled for release 26 September 2025 (though delays in some regions are noted). 
In this set, you’ll see “Mega Pokémon ex” cards return — big, dramatic forms of favourite Pokémon with extra powers, heavy art, and high stakes for battle or collection. 
 

The excitement is real because:

These Mega forms evoke nostalgia (the original Mega Evolution era in the video games and TCG).

They signal a “power bump” in the meta: higher HP, stronger attacks, fresh art.

Collectors have something new to chase: variant art, Elite Trainer Boxes (ETBs), special boosters.

Retailers and players will push them hard — “first wave” sets like this tend to become sought-after.

Why This Matters — For You as a Collector or Player

Collector’s value: Early print runs, special boxes, full-art variants tend to hold value—especially when a mechanic like Mega returns after a gap.

Gameplay impact: If you’re playing the TCG competitively, Mega Pokémon can change strategy: high reward but higher risk. For instance, older Mega cards often required discarding or had trade-offs.

Display & investment: A flashy Elite Trainer Box or a rare Mega card may be a good pick if you’re into collecting.

Region-watch: Because of delays, check UK/EU release dates and retailer info. Being early might get you promo extras or special promos.

Pre-order early: Since this is a big “return” set, it’s likely to sell out or get price spikes.

Check region release dates: UK/EU may differ from US. Delays have been noted.

Promos & special prints: The Elite Trainer Boxes often have promo cards inside. Good to verify what’s included.

Condition matters: If you’re collecting for value, look for sealed boxes, mint promo cards, and keep them protected (sleeves, top-loaders).

Meta vs value: If you play the game, focus on cards with good competitive value; if you collect, focus on rarities and art styles.

Budget vs investment: If you’re just dipping in, get a blister or booster pack. If you’re invested, the full ETB or a rare card may be worth it.
