Well, in the first position i went for Golin Mech which is a common neutral monster with strong melee attack and high mana to stand for sometime in the first position. There were a ruleset of opportunity and common, rare monster should be used in the battle so Goblin mech will not be targetet first.

In the third position, i used the main monster of this week Silvershield bard which is a single mana monster. I used this monster especially for the battle challenge but let me say that i did not win this battle because just checked the opponent summoner and monsters but still i want to share this battle to show my strategy but it did not worked because of the less upgraded summoner and monsters. This monster worked well to remove the negative status form his friendly monster and because of that SHIELDBEARER saved this monster from early death.

Well, the mana was enough so choosing a high mana monster was good like this monster which is also a high mana monster with powerful range attack that i have at level 4 but because of the summoner the range attack of this monster reduce from 4 to 3 :( also while facing the strong opponent with level 3 cards is not possible to win this game but still need to upgrade this summoner will check out the price...

In the last position i used SHIELDBEARER which is a rare monster from the untamed packs edition and i used this in the last position because of its taunt ability that will divert the fous of all enemy monsters and all of them will targeted this monster untill it dies so in this way you can save your other monsters from early death because of this monster but this will work only when you unlock the shield ability and will use a repair monster in addition.
