HS Undaunted
The greatest Trainers are those who are fearless in the face of battle. In the Pokémon TCG: HS—Undaunted expansion, you'll discover battle-ready Pokémon just waiting to be summoned by the fearless Trainer in you! The powerful Rayquaza and Deoxys become Pokémon LEGENDs to be reckoned with and six Pokémon—from Raichu to Umbreon to Slowking—join the ranks of Pokémon Prime. Stadium cards like the Ruins of Alph and Trainer cards like Legend Box change every player's strategy. Are you ready to be Undaunted?
With 90 cards, the brand-new Pokémon TCG: HS—Undaunted expansion is now available in retail stores nationwide.
Features of the new Pokémon TCG: HS—Undaunted expansion:
- All new theme deck packaging featuring clear preview window to see first card in each deck.
- Introduction of Daybreak and Nightfall theme decks with bonus booster pack!
- Rare and Legendary Pokémon teamed up in pairs—Kyogre & Groudon and Rayquaza & Deoxys!
- New amazing Pokémon Prime cards including Houndoom and Scizor!
An Evolution Revolution!
Get ready to take your game in a bunch of new directions with Eevee and its many Evolved forms! Virtually all of Eevee’s Evolved forms are here, including Espeon (2/90), which comes with a Solar Suggestion attack that lets you move up to 4 damage counters among your opponent’s Pokémon in any way you like. And don’t miss out on Espeon Prime (81/90): its Evolution Memories Poké-Body will let you use the attacks of any of the Pokémon that you have in play that evolve from Eevee! Take your pick from a wide range of attacks to suit whatever situation you find yourself in!
The LEGENDs Continue!
Two more Pokémon LEGEND pairs take charge in HS—Undaunted: First, Kyogre & Groudon LEGEND (87/90 and 88/90) storms into play with a pair of powerful attacks that will fit into any Water- or Fire-themed decks. Not to be outdone, Rayquaza & Deoxys LEGEND (89/90 and 90/90) can also deliver punishing blows while—thanks to its Space Virus Poke-Body—taking an extra Prize card every time it Knocks Out one of your opponent's Pokémon! There's no end to the possibilities when you play these outstanding Pokémon LEGENDs!
Legendary Support!
Pokémon LEGENDs are extraordinarily powerful, but they can be a little difficult to get into play. Fortunately, HS—Undaunted solves that issue with a few of excellent Supporter and Trainer cards. First, the Legend Box (75/90) Trainer card lets you look at the top 10 cards of your deck. If you find both halves of a Pokémon LEGEND, you can play them directly onto your Bench. Plus, you also get to attach any of the Energy cards you revealed onto the Pokémon LEGEND! If that’s not enough, check out the Sage’s Training (77/90) Supporter card, which lets you look at the top 5 cards of your deck and keep any two of them...but the other three go in your discard pile. Costly, but one thing to consider: Sage’s Training is a worthwhile gambit if you’re looking to play Pokémon LEGENDs quickly!
