Any red-white aggro deck would want to have Haktos the Unscarred. It is basically immune to any card except one with the chosen converted mana cost of two, three, or four. Of course, you can't choose it yourself, as the effect is random, but it will work in your favor more often than you'd think.
Haktos is always immune to tokens, as zero- and one-cost cards are out of the question. This means that it will be really hard for any opponent to find a specific removal against Haktos, so it should definitely be on your radar.
