For Espo Trooper it says 0 cost. Does that mean that the card still gets focused after It's used?

Also, can I use this card more than once per active turn since it doesn't cost anything?

For Human Replica Droid, it says to put the card into play after I win the edge battle. Does that mean I have to pay for the card after it enters play from winning the edge battle?

Thank you

A card always gets focused after it strikes. It's cost has nothing to do with that. You can play multiple copies a turn if you have them in your hand as the Espo Troopers are not unique.

When you put a card into play it is free. When you play a card you pay it's cost.

Espo is a unit that costs 0 and is not unique.

Therefore, if you have 4 Espo on hand, you can play all of them in the same deploiement phase.

During an engagement, you may déclare any one of them as participating, and you must focus to strike each one of them

Slight clarification on that last sentence: you must focus to strike each one that participates in an engagement.
