relentlessasrats-blog asked: Can you tell us what bloodrush actually does? Since it's an ability word, the preview card is pretty ambiguous at showing which part of the mechanic carries across cards.

Bloodrush essentially allows you to discard a creature to give your creature +X/+Y until end of turn where X is the discarded creature’s power and Y is its toughness. Note that this is all me paraphrasing and is not rules tight.
