The stratagem works because 0+1 = 1.
Thanks for the
FAQ link. I'm still not 100% convinced on the Codex bit however, as the rule seems to state that a condition must be met (your Warlord being from a particular Codex) before you can take Relics from that Codex.
Codex: Adeptus Custodes, Page 76 wrote:If your army is led by an Adeptus Custodes Warlord , you may give one of the following Relics of Terra to an ADEPTUS CUSTODES CHARACTER in your army.
I'm not sure, it does seem to me that the condition in red has to be achieved for you to take Relics.
