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

Description

Brass's Tunnel-Grinder // Tecutlan, the Searing Rift (LCI-373) is a legendary artifact that transforms into a legendary Cave land from The Lost Caverns of Ixalan. When it enters, you may discard any number of cards then draw that many plus one, and it gains bore counters at end steps if you descended to eventually transform. As Tecutlan it taps for red mana and gives a discover trigger when you cast a permanent spell using that mana, letting you potentially cast the discovered card.
