I'd suggest throwing in a few Chained to the Rocks

I would take out 2 lands, and 2 psychic delusions if you want a full set of breaking. It's a tough choice between breaking and psychic delusions, but basically it depends on how many creatures you have that could deal damage, and would they survive long enough to make it worth it. I leave it to you to figure that one out.
One card (or technically, half-card) that comes to mind is Breaking in Breaking // Entering. Its 1 B and 1 U mana to cast, and it mills 8 cards off of an opponent's deck. I think it's pretty good for early game, and I think they could fit in your budget at around 50 cents a card.
