Hi,
There are so called artifacts which belong to no colour. For example if I take my "Ornithopter" (Flying artifact with 0 mana cost)and I enchant it with two "unholy strenght" ( each 1 black mana) I have a 4/4 flying creature for 2!!! mana and I take that angel down imediatly <img src="/ubbthreads/images/graemlins/badsmile2.gif" alt="" />
