Holon Researcher (ex11-95) is a Supporter Trainer from the Delta Species set that requires discarding a card from your hand to play. When played, it lets you search your deck for either a Metal Energy card or a Basic/Evolution δ (Delta) Pokémon card and put it into your hand, then discard the Supporter at end of turn. This card enables consistency for metal or δ Pokémon strategies by tutoring key cards at the cost of a hand discard.
