Sure Strike⁣ - Innistrad: Crimson Vow⁣ (Common)⁣ [179]

Sure Strike is an instant spell that boosts a target creature's power by 3 and grants it first strike until the end of the turn. This means that your creature will deal its combat damage before any opponents’ creatures without first strike, allowing it to potentially take out blockers or deal damage to your opponent before they can retaliate. You’d want to play this card to either push through extra damage in a crucial attack or to ensure your creature survives a combat encounter, but be mindful that it only lasts until the end of the turn, so timing is key.
