Rule #1 of gambling: The House always wins.
Slot Machine is the custom card designed by 2017 champion Wilfry Horig, and boy is it interesting!
With a rez/str ratio of 3/5, its already worth a look, and with 3 subs and priced at a single influence, its almost TGTBT. When looked at a little closer, however, it gets a little worse.
Encounter effect: Bottoming a card is useful but will rarely be game threatening. If its a critical icebreaker then the runner may have to dig for a tutor but most of the time they won't care about losing something random. However, this does get significantlu better with any sort of draw seal or a Kala Ghoda Real TV on the board. Furthermore, the information for knowing the next 3 cards is useful but not critical as well.
-> The runner loses 3
This sub is always useful, as making the runner lose money is important for any economic war, especially out of Spark Agency: Worldswide Reach. This sub also immediately evens out the cost.
If two of the cards..
This is where the ICE gets weird. Ensuring 2 of 3 random cards from the runner's deck isnt impossible: Many runners pack more Resources and Events than other types.
If 3 of the cards... This one will amost never happen, and if it does, what are you going to use those counters on? Importing into Weyland could work, or using a False Flag, but realistically you can't count on this sub.
One final note
1 influence, 3 rez, 3 subs. 5 strength. Nobody actually wants to break this ICE. Yup.
