Still think it will be far too situational... The only things which give delay are Basilisk's Blood (yes I stand corrected) and Turtle Shield...
How often do you come across someone using purely Basilisk's blood for creature control? I certainly haven't, at least not recently anyway..
Might be useful in un-time-bubbling one of your creatures after it has attacked a Turtle Shield.. But he will just get 'delayed' again next turn... So all in all, would I put 6 of these in my deck 'just incase'? No.
