Trial // Error⁣ - Dissension⁣ (Uncommon)⁣ [158]

Trial // Error offers two distinct effects: the first half, Trial, counters a target spell unless its controller pays {2}, while Error allows you to return a creature to its owner's hand and then draw a card. This flexibility makes it valuable in control decks, providing both a countermeasure and a way to deal with threats while maintaining card advantage. However, it requires careful timing and resource management to maximise its potential.
