two-of-a-kind

Identical duo together

Two-of-a-kind describes a pair of things that are alike or uniquely matched: Those sisters are two of a kind.

In card games, it's a hand containing exactly two cards of the same rank.

Outside cards, the phrase usually emphasizes similarity in character or behavior, often with affection or mild criticism: You and your brother are two of a kind—always causing trouble.
