I dipped anyway, got Firewall and 2 each of the new Trickstars. Then dipped into that box for 2 each of the Trickstar UR and SR cards. I'd say it was worth it. Now to save Gems for Firewall support.
Limit Code can summon It by having 1 link in the GY (Link Disciple, link1 counts), then summon any link3 with Limit Code, and you only need 1 more Monster to summon Firewall.
