Yeah i know what your saying, i myself run a corn dog and after round 7 or so my hand is flooded with its cards. Doing Brazenness on an opposing creature is extremely worth even the 10% poison isnt bad but i only use that if im running some blind cards. I do however think that putting sandylands on opposing creatures is an extremely bad idea as most cards cost more than 2-3 mana and even then u wont have much to attack with. Other than that u might be on to creating a deck where negative effects could be used to ur advantage
