Jeeeeez, talk about a punishing facecheck...
Tyr is the newest addition to ice based on the Norse pantheon, with others being Wotan, Loki and Heimdall. Like its siblings, Tyr is big and expensive, with scary subroutines but also the ability to click through them.
Not that you would want that in this case. Unlike other bioroids, any click you spend on Tyr will go to the corp, which is a very raw deal for the runner. Even just giving the corp 1 extra click could mean they could be fast advancing a Vitruvius on their next turn. Giving the corp 3 clicks is potentially game ending, as 6 clicks allows them to score a 5/3 from hand, or do other shenanigans.
Letting the subroutines fire isn't really option either though. Two brain damage is nothing to sneeze at, as a permanent handsize of 3 is a big hinderance. Having the corp gain 3 credits AND trash any card they want is extremely powerful and especially in the mid or late game could cause a huge swing. The final sub is a good ol' ETR, always welcome on a big ice, and the only one you can afford to let fire in most circumstances.
I think this bioroid is definitely worth its cash, and a great new tool for purple glacier. 5 influence means it is difficult to slot in other factions but I think that's a good thing. This ice has HB written all over it.
Also, take a moment to appreciate the art on this one. It is gorgeous.
