Spurred Wolverine

The cost line tells the whole story: tap two untapped Beasts you control, with no tap symbol on the ability and a creature type that qualifies it to feed itself. That last detail is the only thing keeping the ability from being dead in isolation; Spurred Wolverine can tap itself as one of the two, so a single other Beast is enough to grant first strike. Even so, the math rarely favors using it. First strike wins the trades where your attacker or blocker is one toughness short of surviving, but spending the activity of two bodies to upgrade one fight usually leaves you down more tempo than the saved creature is worth. A 3/2 for five is well below the curve, so this is not a body you build around; the ability is the entire pitch, and the pitch is conditional. This is the kind of tribal filler the early era leaned on to give a creature type texture below the rare slot: a mechanic that names the Beast tribe and rewards a wide board without ever being efficient enough to change how the deck attacks. The effect is genuine and the self-tapping clause makes it less of a trap than it first reads, but the cost structure ensures it stays a corner-case sweetener for boards with Beasts to spare, not a tool you sequence toward.
