Splinterlands Battle ConsiderationsVol1 Cost15,Weakening of magic,Ban on recovery

What do you think?

I thought black was strong because of its low cost (15).
And since magic attacks are weakened, I decided to include a monster that removes shields.
The strategy is to reduce the HP of the opponent's monsters and defeat them with one damage to the whole.
However, the enemy had the same strategy.

As a result, I won by a difference of Summoner.
