Damage loop: each card converts the other's damage into more triggers, repeating arbitrarily. The pair can't keep the loop going alone — this card supplies the missing piece.

Generic synergy — paired produce/consume of the same primitive. The pair can't keep the loop going alone — this card supplies the missing piece.

Untap loop: each card untaps the other, generating arbitrary activations or mana. The pair can't keep the loop going alone — this card supplies the missing piece.

Refuel loop: one card's payoff untaps your lands, paying for the other's activation again — repeatable every turn, and often infinite. The pair can't keep the loop going alone — this card supplies the missing piece.
