Agree about the playtesting. Also, might be good to limit the use of the cards to the early part of the game. 4 turns? Anyway, before the battle gets to the chaos phase. For Mongols the orders would be, "Do this and if it doesn't work get out of there."
I suspect you're thinking about battle cards as events that are "played" (held in reserve until expended to create a game effect at a particular time); relatively few battle cards currently under examination have that structure. The vast majority are army-specific or stand-type specific abilities like mid-battle dismounting, pre-battle dismounting, mounted infantry of various types, Plaustrella, deployment enhancements, fortified camps, distant/absent camps, Standard Wagons (Carroccio), and that sort of thing.
There are some "play it" battle cards -- "Hold the Line", for example, is an expendable battle card (one that is played, and after played is no longer available) that allows a player to avoid following up on an enemy stand that his guys double, where normally he would advance forward. Some particularly disciplined foot (Roman Legionaries, for example) have or can purchase that card. But most battle cards aren't built that way.
