Equipment that draws cards on connection is old hat; what this one does is make the payoff scale with a stat the game rarely rewards you for tracking directly. The trigger counts modified creatures, and the reminder text spells out the currency: Equipment, Auras you control, and counters all qualify. So the card is not really asking "did a creature hit," it is asking "how wide is your board of enhanced things," and then paying you that many cards off a single connection. The distinction matters: only the equipped creature carries the combat-damage trigger, so this is not a wide-attack engine that stacks draws per attacker. It is one bomb of a hit whose yield is inflated by everything else you have gone tall on: every creature carrying a counter, an Aura, or an Equipment counts toward that one draw, whether or not those creatures are attacking. The self-attaching enters clause matters more than it looks, too: the card equips for free on arrival, so the four mana buys both the +2/+2 (which makes the equipped creature count as one, since it has Equipment attached) and an immediate combat threat without the usual second-turn equip tax. The friction is that it wants a specific kind of board to be worth its mana, one already invested in auras and counters, and it does nothing to build that board itself. It rewards a shell that was already going tall-and-wide, then converts the overflow into cards.
