As you know, one of the most important things to keep in mind is the rules of the game. In this case, there is no healing, all creatures have the blast ability, we have 99 mana, and water or earth splinters can´t be used.

As one of the conditions is that all creatures have explosive attacks, I decide to use Lorna Shine as a summoner. That divine shield it provides will make my creatures take fewer hits and give them more time to deal damage to the opponent's. As a first line I use the Shieldbearer because he has the ability to provoke and he will receive all the attacks and I can control that the explosions damage the creatures that I want . 

In the second line I put the challenge card since thanks to the shield ability it will receive less damage from the physical attacks that the Shielbearer receives and if it attacks as it is a 99 mana game, it is likely that there will be creatures with more than 10 mana so his giant killer ability will come into play. Then I put the Djinn Renova since it has a good magic attack and it will give me an extra life that I will need to beat my opponent.  

Then I put Adelade Brightwing because since you can't heal the recover shield with her ability, it will come in handy and she also has to resurrect which will make the Sieldbearer last a few more turns and continue attracting attacks. Bila the Radiant is my next card since with the explosive attack she increases her ability to gain life which will make it take a long time to kill her if the case arises.

 

The last card used is High Priest Darius since he has a good attack and also resurrects, what more can you ask for.

As you can see, my rival had the same idea as me and used a card with provoke to attract the attacks, the only thing that he put was the last one, which made my magical attacks go to that line and the physical ones to the first. The damage was divided a bit and that could have hurt me but the good thing is that thanks to the double resurrection and the shield of the Chaos Knight I gained enough time for the Grum not to kill anyone since that could have been the end of the game . Also, the Chaos Knight gave him a good hit thanks to his giant slayer ability which helped a lot since his void could have done a lot of damage to my mages.
