Dash

Dash is a keyword ability on permanents that allows the player to play the card for an alternative cost. When you pay its dash cost instead of paying its mana cost, the creature will have haste, so it can attack that turn. At the beginning of the next end step, you'll return the creature from the battlefield to its owner's hand.
==Description==
Dash was introduced in Fate Reforged where it replaced Raid from Khans of Tarkir as the mechanic associated with the Mardu Horde. It also features in Dragons of Tarkir, associated with Clan Kolaghan. Without the keyword, the nonoptional concept was featured as early as Visions, on <c>Viashino Sandstalker</c>.
Dash costs are all one mana's difference than the converted mana value, and whether that difference is higher or lower is largely dependant on context. The typical trend is that Dash costs pull towards the middle of the mana curve into the 2-3 mana spot: cheaper ones use costlier Dash as superior utility late in the game, while expensive ones use cheaper Dash as a bonus when missing a spot on the curve. Dash costs at 4 all have high impact attack or entry triggers, or in the case of <c>Pitiless Horde</c> and <c>Sprinting Warbrute</c>, use it as downside mitigation.
Dash also appeared in Modern Horizons on the first and only green card. It also reappeared in the March of the Machine Commander Decks.
==Rules==
==Rulings==
* If you choose to pay the dash cost, you're still casting the spell, so it goes on the stack and can be countered. 
* Dash doesn't change when you can cast creature spells — usually only during your main phase. 
* If you cast a creature spell using its dash cost, it will return to your hand only if it's still on the battlefield at the beginning of the next end step. If it leaves the battlefield before that point, it'll just stay wherever it is.
* You don't have to attack with the creature with dash unless another ability says you do.
* If a creature enters the battlefield as a copy of or becomes a copy of a creature whose dash cost was paid, the copy won't have haste and won't be returned to its owner's hand.
