A lot of these Lannister strategies suggest using Kevan Lannister's ability of increasing the strength of footmen to 2 for an attack. Please keep in mind that Kevan's card clearly states that this ability only works for DEFENDING, not ATTACKING. Victarion Greyjoy's ability is so much better because he does not have any restriction like this. It does seem like the Lannister House Cards are weak in comparison to others like the Greyjoys. Victarion and Balon have very powerful abilities.
