Saburo Arasaka: Stubborn Patriarch

How this card works

Saburo Arasaka: Stubborn Patriarch has no cost or power. He is a static effect that starts working once he is face-up: friendly ARASAKA Units have +1 power while attacking. The reminder on the card explains why that matters, since Units steal an extra Gig for every 10 power.

That single point moves thresholds. Minotaur, at 9 power, attacks as a 10 and steals two Gigs instead of one. Yorinobu Arasaka: Steel Dragon does the same, and when played it can also play a Unit with cost 4 or less from your hand or trash for free.

The FAQ clarifies that the +1 applies in both the fight and steal steps, where the 10 and 20 power thresholds are checked. It does not help on defence or when blocking, only while attacking. His bonus only works while he is face-up, so you want him revealed early.
