Goblin Mech has the strongest melee attack and shield. At the moment l think that it's the strongest card and also only card which costs 10 mana. I don't think any other tank can win Goblin Mech if you test which tank is better 1 VS 1. At maximum level Goblin Mech has 10 mana but if you use The Peakrider and Defender Of Truth then he will have 12 shield which is awesome. You can also increase melee attack of this card with using Pixie and Silvershield Knight where this card will have 8 melee attack to eliminate the enemy with just one attack.
