pokemon energy cards first edition Charge Basic Energy Rarity 1999 Pokemon Base Set Shadowless

At least for playtesting

Features: Set comes with two booster packs from the The Two Legends release

Rite of Replication or Myojin of Cryptic Dreams can get you there unconditionally in one card, while Echoing Equation and Mirrorweave are more battlefield-dependent

It also has hexproof from each color for added protection, and annihilator 2 tacked on for good (and thematic) measure

Among the Legendary Creatures in the set there was a cycle of Elder Dragons

Sword of Once and Future ($30) Its really unfair that the first Sword of X and Y basically got you two cards worth of value on the first hit, because every Sword after that has had to live up to that standard
