If it’s the turn Stampeding Horncrest comes under your control, and it loses haste after being declared as an attacker, it will continue to attack. It won’t be removed from combat. On the other hand, if it loses haste before your declare attackers step, it won’t be able to attack.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
