This deck appears to be a rainbow rush with wardens for defense. Don't hamper your rush by squeezing in more defense - trust your wardens, and RUSH!
I don't know if I understood you right...
but my idea was to kill the enemy creatures with wardens by blessing them.
This makes the attack slow, especially in the beginning because there are only spiders to damage.
So you meant to rush with blessed spiders and stop the enemy with wardens?
Interesting! I guess both strategies work!
And indeed, I wanted the warden to stop creatures, not a shield, so personally I won't add Wings
