I'm using a water Splinter for this Battle which is Alric Stormbringer. Its special ability is to increase +1 magic attack on the cards with magic.
My line up
Just like my strategy on my previous battles, I'm putting the cards with a good number of shield on the front line. This is to make sure the the other cards are somehow protected. Next line is the Wave Runner. I placed it on the second line because it has the reach ability which can make sure that he will make an attack while it is not on the front line. Cards with the reach ability are good in the second spot(if I'm right haha). Next is the sabre shark, I placed it in the middle so it is not that open to any attacks. Making sure that he can attack the back line of the enemy little by little. It only has 2 Life so I have to secure it if I want to make him survive. Next line, the Crustacean King. It has a healing ability, this will make sure that the front line will revive everytime they were attacked. Last spot, the Ice Pixie this is a crucial move because Ice pixie only has one life. It will be easily attacked by enemy's card with sneak attack. Luckily, my opponent did not use any cards with sneak ability.
For me, I did a great start here since I won plus all of my cards managed to survive the whole round.
