Explore usually lives on creatures that grant the trigger once, on entry: a single dig, a single counter, and the effect is spent when the body enters. Stapling it to an Equipment changes the accounting entirely. The trigger recurs on every attack, and it moves between bodies for two mana, so the same green pip that would buy you one explore now buys a permanent that keeps exploring on whatever creature is swinging. That reframes it as a slow value engine: attack after attack, you either draw a land or grow the equipped creature while filtering your draws. The library-peek clause is the quieter half of the design, turning explore's card selection into standing information rather than a single glimpse, which lets you sequence draws and know in advance whether the next swing hands you a counter or a card. The tension the design has to manage is that an Equipment costs tempo twice (once to cast, once to equip) and the payoff arrives only in combat, so it wants a board committed to pressing rather than trading blows. What it rewards is repetition: recurring explore triggers pay off width in a way the enters-the-battlefield version never could, since a dead creature stops exploring but the Equipment simply latches onto the next attacker.
