About Trial // Error
Trial // Error, Instant , designed by Ron Spears & Wayne Reynolds first released in September 2022 in the set Commander 2016 and was printed exactly in 2 different ways. It's currently being selled by the minimum price of 64.66.
A deck that focuses on controlling the board and disrupting the opponent's strategy would benefit from using Trial // Error in a multicolored deck. While this card offers versatility by returning creatures to hand and countering multicolored spells, it may not be as efficient as other options like Cryptic Command or Teferi, Time Raveler which offer more flexibility and impactful effects. However, in the right meta or strategy, Trial // Error could see play as a niche sideboard option for specific matchups where its abilities shine.
Rules
12/08/2022
A split card's characteristics are a combination of its two halves while it is not on the stack. For example, Assault // Battery has a mana value of 5 while it is in your library. If an effect allows you to search your library for a card with mana value 4 or less, you can't find Assault // Battery.
12/08/2022
Each split card has two names. If an effect instructs you to choose a card name, you may choose one of those names, but not both.
12/08/2022
Each split card is a single card. For example, if you discard a split card, you've discarded one card, not two. If an effect counts the number of sorcery cards in your graveyard, Assault // Battery counts once, not twice.
12/08/2022
If an effect allows you to cast a spell with certain characteristics, consider only the characteristics of the half you're casting. For example, if an effect allows you to cast a sorcery spell with mana value 2 or less from among cards in your graveyard, you could cast Assault this way, but not Battery.
12/08/2022
If you copy a spell that's half of a split card, the copy copies that same half. For example, if you copy Assault, the copy is also Assault, not Battery.
12/08/2022
Split cards have two card faces on a single card. The characteristics of the half you didn't cast are ignored while the spell is on the stack.
12/08/2022
To cast a split card, choose one of its halves to cast. There's no way to cast both halves of this split card.
