I completed Tricky Europe V2 in 25 turns.

Video has a detailed strategy.

I used a Sanction Card on Gadaes on Turn 7 (in effect for Turns 8-14).
On Turn 14, I invade Tingus against no opposition.

I lure and trap Durocortorum's large army at Colonia Agrippinensis on turn 19
Then bait and kill it on turn 24.

A miscalculation prevented a 24 turn win.

Other potential Sanction Card Strategies.
1. Turn 1 Sanction Card on Gadaes - This allows Qssonoba to take the Mauretania bonus on turn 8 and Gadaes can start fighting back. Entering Tingus is tougher, but the mop-up of North Africa is easier.
2. Turn 6 Sanction Card on Gadaes - This allows for an easier walk to Gadaes, but you meet a 22 army reinforcement at Tingus.

Edit:
I won in 22 turn. I made a YouTube video.
