Brass's Tunnel-Grinder // Tecutlan, the Searing Rift | Legendary Artifact // Legendary Land | // Cave | When Brass's Tunnel-Grinder enters, discard any number of cards, then draw that many cards plus one. At the beginning of your end step, if you descended this turn, put a bore counter on Brass's Tunnel-Grinder. Then if there are three or more bore counters on it, remove those counters and transform it. (You descended if a permanent card was put into your graveyard from anywhere.) // (Transforms from Brass's Tunnel-Grinder.) {T}: Add {R}. Whenever you cast a permanent spell using mana produced by Tecutlan, the Searing Rift, discover X, where X is that spell's mana value. | Cristi Balanescu

Breeches, Eager Pillager | Legendary Creature | Goblin Pirate | First strike Whenever a Pirate you control attacks, choose one that hasn't been chosen this turn — • Create a Treasure token. • Target creature can't block this turn. • Exile the top card of your library. You may play it this turn. | Josu Hernaiz
