Tech Choice

A card chosen for its strength against a certain matchup or mechanic, as opposed to synergy.

A tech choice is a card used in a deck not because it is synergistic but because it can help against a specific matchup or card mechanic that is unfavorable for the deck. This is often done when a particular deck or card is popular or OP in a meta or when a player targets a specific deck or archetype during tournaments. An example is teching a row effect clear if row effects are widely used in the current meta.
