They're both cards to avoid imo, Junta needs power to win with and both of these cards boast a pathetic 5.
Apart from winston, La Junta only start getting decent from Tank onwards in cost.
Cheapest I would advise would be
Winston, Tank, Dean, Trish.
This again may look low in power but winston and tank can both be played well defensively (to stop damage and extra abilities from cards) and the SoA and -power on the last 3 can greatly help to win rounds as well.
