Operation Focus Points: Fire Deck

So I posted last week that I thought the new focus point system was pretty impossible for low profile players such as myself. I got quite a bit of response and tips and despite feeling disheartened at first I decided to go for it!

I got a fire focus and to be honest, fire is not my strongest suit, but who doesn't like a challenge?

So I went on the rental market and rented the following cards:

I quite like this card actually! The stand alone function makes it pretty strong. I would have loved it if it had an extra attack, but soit.

I also really like this card! It is a handy card and when used with Tarsa gives a nice amount of attack!

Then I got a bit silly and also rented:

Which is really cool when it works, but doesn't actually work all that often...

And the conclusion so far is that I am struggling! It is hard to try to win battles without using the standard cards (because you won't really get any focus points) but still make a decent deck. I have been playing for an hour now and have gathered 14 of the needed focus points....

So any tips and tricks are more than welcome, good fire deck tips are very much needed!
