Equipment that generates energy on attack, then spends that energy on a coin flip: this is a deliberate collision of three mechanics that rarely share a card. The energy accumulation is passive and reliable, but the payoff gates itself in two ways. First, you only get the option when your creature is blocked, so the removal is defensive-turned-offensive, punishing an opponent for stopping your attacker rather than clearing a path. Second, the flip splits the outcome hard: winning exiles the blocker outright (past indestructibility, past death triggers, past graveyard recursion), losing deals a single point of damage and mostly wastes the two energy. That variance is the whole cost structure. An unconditional exile stapled to an attack trigger would be far too clean, so the design pays for the exile clause with a fifty-fifty gamble instead of a mana premium. The +1/+1 keeps the equipped creature relevant in combat while the energy quietly stockpiles, meaning the coin-flip activation is a bonus layered on top of a body that already wants to attack, not a payoff you have to build around. It rewards repeated attacking without demanding it, and it turns the attack step itself into the resource-generation engine rather than a separate ramp piece.
