I am looking for help with reviewing sets and/or maintaining Lore Seeker and the Big Custom Box. If you're interested, please contact me in #general in the Custom Standard Discord. —Fenhl
Whenever you cast a Trap spell, Trapmaker's Detonator deals 2 damage to any target. If you cast that Trap for an alternative cost, Trapmaker's Detonator deals 5 damage to that permanent or player instead.

Decipher, flashback, and "without paying its mana cost" are alternative costs. Each Trap card also has an alternative cost.
Additional costs, cost increases, and cost reductions (such as the one from Joraga Snaresetter) are not alternative costs.
