Brass's Tunnel-Grinder // Tecutlan, the Searing Rift

Description

Brass's Tunnel-Grinder // Tecutlan, the Searing Rift is a Legendary two-faced card from The Lost Caverns of Ixalan that begins as a red artifact and can transform into a legendary Cave land. As the artifact, it provides card selection by letting you discard any number of cards then draw that many plus one and gains bore counters when you descend to eventually transform. As the land, it taps for red and triggers a discover effect when you cast a permanent spell with mana produced by it, potentially letting you cast that discovered permanent.
