Grevas Faiscantes

Text:

A criatura equipada tem ímpeto e não pode ser alvo de mágicas ou habilidades.
Equipar (: Anexe a uma criatura alvo que você controla. Equipe somente quando pudesse jogar um feitiço. Este card entra em jogo solto e permanece em jogo se a criatura sair de jogo.)

Rulings:

• 8/7/2020 You can’t simply unequip Equipment from a creature. If Lightning Greaves is attached to the only creature you control, you won’t be able to attach other equipment to it (or target it with anything else) until you have another creature onto which you can move Lightning Greaves.
• 8/7/2020 If a creature enters the battlefield under your control and gains haste, but then loses it before attacking, it won’t be able to attack that turn. This means that you can’t use one Lightning Greaves to allow two new creatures to attack in the same turn.
