What is flash in mtg?

Flash is a keyword ability in Magic: The Gathering that allows a player to play a card from their hand at an unexpected moment. This means that the card can be played at any time, such as during an opponent's turn or even in response to another spell or ability.

When a player casts a spell with flash, it doesn't follow the normal timing restrictions for casting spells. Most spells can only be cast during the player's main phase when the stack is empty, but flash allows cards to be played at other times. This can lead to surprise plays and can be a powerful tool for disrupting opponents' strategies or quickly responding to threats.

Flash is commonly found on creature cards, enchantments, and instants. Having creatures with flash allows a player to surprise their opponent by blocking an attacking creature or even summoning a creature to defend themselves during an opponent's turn. Enchantments and instants with flash can be used to counter spells, destroy permanents, or provide other strategic advantages.

Flash also synergizes well with abilities like "enters the battlefield" or "leaves the battlefield" triggers. For example, a creature with flash that has an "enter the battlefield" ability can be played in response to an opponent's spell, gaining immediate value or disrupting their plans.

Overall, flash is a versatile and powerful ability that provides players with the flexibility to make unexpected plays and outmaneuver opponents during the game of Magic: The Gathering.
