When Brass's Tunnel-Grinder enters,
discardTo discard a card, move it from its owner’s hand to that player’s graveyard.
By default, effects that cause a player to discard a card allow the affected player to choose which card to discard. Some effects, however, require a random discard or allow another player to choose which card is discarded.
If a card is discarded, but an effect causes it to be put into a hidden zone instead of into its owner’s graveyard without being revealed, all values of that card’s characteristics are considered to be undefined. If a card is discarded this way to pay a cost that specifies a characteristic about the discarded card, that cost payment is illegal; the game returns to the moment before the cost was paid (see rule 733, “Handling Illegal Actions”). (CR 701.9) 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
counterTo counter a spell or ability is to cancel it: remove it from the stack without resolving it. A counter on an object or player is instead a marker that changes characteristics or interacts with rules or abilities; for example, a +1/+1 counter modifies a creature’s power and toughness.

transformTo transform a permanent, turn it over so that its other face is up. Only permanents represented by double-faced tokens and double-faced cards can transform. (See rule 712, “Double-Faced Cards.”)
Although transforming a permanent uses the same physical action as turning a permanent face up or face down, they are different game actions. Abilities that trigger when a permanent is turned face down won’t trigger when that permanent transforms, and so on.
If a spell or ability instructs a player to transform a permanent that isn’t represented by a double-faced token or a double-faced card, nothing happens.
If a spell or ability instructs a player to transform a permanent, and the face that permanent would transform into is an instant or sorcery face nothing happens.
Some triggered abilities trigger when an object “transforms into” an object with a specified characteristic. Such an ability triggers if the object either transforms or converts (see rule 701.28) and has the specified characteristic immediately after it does so.
If an activated or triggered ability of a permanent that isn’t a delayed triggered ability of that permanent tries to transform it, the permanent does so only if it hasn’t transformed or converted since the ability was put onto the stack. If a delayed triggered ability of a permanent tries to transform that permanent, the permanent does so only if it hasn’t transformed or converted since that delayed triggered ability was created. In both cases, if the permanent has already transformed or converted, an instruction to do either is ignored.
Some spells and abilities refer to a “transformed permanent.” This phrase refers to a double-faced permanent on the battlefield with its back face up. A permanent with its front face up is never considered a transformed permanent, even if it had its back face up previously. Similarly, an object represented by more than one card, such as a melded or merged permanent, is never considered a transformed permanent, even if it has components that are back face up. See rules 701.42, “Meld,” and 730, “Merging with Permanents.” (CR 701.27) it. (You descended if a permanent card was put into your graveyard from anywhere.) // (Transforms from Brass's Tunnel-Grinder.)

Whenever you
castTo cast a spell is to take it from the zone it’s in (usually the hand), put it on the stack, and pay its costs, so that it will eventually resolve and have its effect. A player may cast a spell if they have priority. See rule 601, “Casting Spells.”
To cast a card is to cast it as a spell. (CR 701.5) a permanent spell using mana produced by Tecutlan,
discover“Discover N” means “Exile cards from the top of your library until you exile a nonland card with mana value N or less. You may cast that card without paying its mana cost if the resulting spell’s mana value is less than or equal to N. If you don’t cast it, put that card into your hand. Put the remaining exiled cards on the bottom of your library in a random order.”
A player has “discovered” after the process described in 701.57a is complete, even if some or all of those actions were impossible.
If the final card exiled during the process described in rule 701.57a has mana value N or less, it is the “discovered card,” regardless of whether it was cast or put into a player’s hand. (CR 701.57) X, where X is that spell's mana value.
