Tyrion Lannister
Reviews

Arguably the best card released in the Lannister core set. Stealth in the core only environment is amazing but throw in Tyrion’s gold generation and synergy with the powerful, and in Lannister, omni-present ambush keyword and you’ve got the shining star of core set Lannister. This synergy with ambush will continue to get better as the card pool expands thanks to cards like The Hound.

Important to remember that you get the 2 gold even if your opponent is one that initiated the intrigue challenge. At worst the gold is worth an extra two points for determining dominance.
