Overview

Lost Thunder is a 236-card expansion from the Sun & Moon series, released on November 2, 2018. The set features GX and Tag Team GX cards alongside the standard mix of Pokemon, Trainer, and Energy cards. Notable cards include Lugia GX, Mimikyu GX, Alolan Ninetales GX, Genesect GX.

Best for

  • GX-era collectors tracking full arts and rainbows
  • people attempting a wide Lost Thunder master set who will split base numbers from high-number / special rows
  • people building around Lugia GX / Mimikyu GX without pretending bulk pays the same

Skip this path if

  • you want SV-only rarity language and nothing earlier
  • you want a weekend master set — Lost Thunder is 236 cards; budget the chase tier alone

Common mistakes

If you only remember one thing about Lost Thunder: Lugia GX / Mimikyu GX is not interchangeable with every other print of those Pokemon. People still get burned by reading secret rare numbers wrong and buying the wrong full art, then argue condition after they already overpaid. Confirm sm8 / the set symbol before comps — “SM GX era lot” language is how wrong products get mixed.

What to check first

Verify set membership (sm8) and the secret number row separately from the main set checklist. Condition pass on Lugia GX / Mimikyu GX before negotiation. Finish with a checklist gap list so you are not “completing” only the bulk.

Most valuable cards

The top chase cards from Lost Thunder include Lugia GX, Mimikyu GX, Alolan Ninetales GX. Full art, secret rare, and alternate art variants carry the highest premiums. Other collectible cards include Genesect GX, Tyranitar GX, Sigilyph GX. Condition matters — near-mint copies command significantly higher prices than played cards.

Tips to finish the set

At 236 cards, Lost Thunder is a large set that requires patience to complete. Buy singles for the rarest cards rather than chasing them through sealed product. Start with the common and uncommon base, then work through the holo rares. Secret rares and full arts are best purchased individually.
