Lore

Why it matters

As a rare enchantment from the Mirrodin set, this card functions by granting all creatures haste, a mechanic that allows them to ignore summoning sickness and attack the moment they enter the battlefield. Collectors prize this card for its ability to drastically increase the speed and aggression of a game, making it a powerful tool for those looking to exert immediate pressure on their opponents.

All creatures have haste.

The sooner you see the whites of their eyes, the sooner you'll spill the red of their blood.
