Both seem like strong identities. Tenma is kind of boring-- his main purpose is merely to synergize with a large number of events that people already want to play. It’s a good synergy, though, and the extra influence will help import strong events from out of faction.
I definitely anticipate him seeing play, perhaps with support from PrePaid Voice PAD. If you play a Dirty Laundry for 1, get 1 back, and then gain 5+1 from Desperado, that’s 6 credits for a run you may have wanted to make anyway-- and even if not, 6 credits for 1 click is ludicrous!
Stirling is much more interesting. His ability provides a strong economic benefit, especially against decks that try to score agendas early (Weyland often wants a quick Hostile Takeover to turn on Archer). He has an interesting potential synergy with Data Dealer and perhaps a slower, control-based playstyle. I would be really excited about this identity in Anarch-- it’ll be interesting to see how it does in Criminal.
