Bind

Stifle gets all the credit as the premier answer to abilities on the stack, but green tried a narrower version of the trick and tacked a cantrip onto the back. The difference is the cost and the refund: where Stifle asks a single blue for a catch-all that can stop triggered abilities too, this pays full green freight, restricts itself to activated abilities only, and hands you a card back, so the exchange comes closer to free even when the ability you stop was always going to be one-shot value. The draw clause is the point. A pure ability-counter is a precision instrument you hold for a specific moment and feel bad maindecking, because it does nothing when the opponent simply never activates anything worth answering. This one still carries that same requirement (it needs a valid activated ability already on the stack to cast, and it fizzles only if that ability is itself removed from the stack before this resolves), but when it does connect, the card you draw forgives the narrowness. It is a quietly green piece of design, too: green rarely interacts with the stack at all, and when it does, the color's instinct is to pay a little extra and recoup a card rather than trade flat. The mana-ability exclusion noted in the reminder text is the line that keeps it from warping the color's relationship to acceleration, since countering a ramp player's rocks for a card would do exactly that.
