You say <tt> but if <tt> is an enemy it is an invalid target for "Lady of Crowns" so it falls back to the default target (yourself) and skips the normal line.
You need to switch /ac "Minor Arcana" <tt> and /ac "Minor Arcana".
Now you say <t> for Lady and Lord. For Lady it operates like it should and uses it on the target and for Lord it says invalid target ignores the line and goes to the next one which is <tt>.
This should work as you intend it./micon "Minor Arcana"
