Runners who want money use these cards. So all runners use these cards.
The thing is, the rule of this game already gave you somewhat useful-and infinite-economy: click for credits.
1 credit/click. You can always do this. Every other economy cards should be MUCH better than this ratio.
Dumb calculation. You can net 11 credits from Armitage. (12 minus 1) Sounds cool. What did it cost? Everything...... 1 click to draw, 1 click to install, 6 clicks to get all credits on Armitage. Result: 8 clicks for 11 credits. 1.375 credit/click. (Why am I calling it 'Dumb' calculation? Because some smart people always argue that 'draw' should be less than 1 click... but I don't care because I'm dumb.)
So why not armitage? 1.375 credit/click sucks. And spending eight freakin clicks for 1.375 credit/click really sucks.
So why Liberated? It's 10/6, 1.67 credit/click, and pays you back quite fast. So why Daily Cast? It's 5/2, 2.5 credit/click. You must wait for it, but ratio is just fantastic.
...and now Malia kicks in....
Case one. Runner doesn't care about their kidnapped economy. Well nice, You just spent 6(3) credit and one click and one card for nothing but my kidnap-bioroid. Yum Yum.
Case two. Runner tries to get back their economy paying some ransom. Another dumb math time. Liberated? (10-3)/(6+1), 1 credit/click. Dailiy Cast? (5-3)/(2+1), 0.67 credit/click.
Wow, it becomes more ridiculous with some ice and upgrades. Sometimes runner should forget about their past,-and be hard at work, click for credits, otherwise they'll-have to click for removing tags.
Thus, I like Malia as an asset form of Economic Warfare. But it baits run, rather than requires run.
