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

Description

Brass's Tunnel-Grinder // Tecutlan, the Searing Rift (LCI-373) is a legendary artifact that can transform 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 when you descended to eventually transform. As Tecutlan it taps for red mana and triggers a discover effect when you cast permanent spells with its produced mana, enabling card selection and potential free casts.
