I'm interested and I DON'T run madness, so I think this card might be dangerousView attachment 8957
Whenever you attack, you may discard a card. When you do, put a +1/+1 counter on target creature. That creature gains trample until end of turn.
Whenever you discard one or more cards, exile the top card of your library. You may play that card until your next end step.
I think it might be too good for me, sadly, with the second effect on top, but damn that's a great aggro madness card.
That being said, if you want to make something powerful, the non-wild mongrel madness colors are probably a nice place.
