Too bad you can't use a Khalitzbooby card when equipped with a HF.

Also, I think the best card for a HF MVP wise is AK. It's 25% increase damage. TG's 20% ATK is good for all-around, but in PVM you don't need that kind of damage and you also need a shield. And Drake is not the best choice since, as people stated, the most important MVP's are large, so Drake only helps with MVP's that probabley aren't worth the higher damage.
I would go AK. I would probably save a TG for a GX weapon, like a +12 FQL :3
