Agor Longtail is definitely one of these cards that you need in high mana battle. Imagine if you pair it with a resurect card... ! I love this tank but unfortunately I don't own it yet :-)
I have picked this post on behalf of the @OurPick project and it will be highlighted in the next post! 
I should have mentioned that Resurrect works really well with Void Armor. It's a real pain for your opponents to have to go through the full shields again.
These days there are so many different cards that it seems impossible to own them all.
