Splinterlands Challenge - Share Your Battle - Gelantinous Cube

This is my first participation in a share your battle challenge. In last week's challenge I could not participate due to lack of cards, but this time I had collected enough DEC and I could buy the Gelantinous cube in the market.

This is the setup I chose for the earthquake rule with 24 mana.
I placed the Gelantinous cube between the meele and ranged cards.

In the first round all monsters have survived and have lost some lives.

In the second round three enemy monsters and my Death Elemental died and therefore regenerated my cube well.

In the third round two more enemy monsters and my Elven Defender died and so the cube could generate more Health Points and still had 5 Health Points after the earthquake.

On the last turn, the only remaining enemy monster only has 3 remaining Health at the beginning. It lost two of them due to the earthquake and my Tower Griffin then dealt the death blow.

Whether I have chosen an optimal strategy or I was just lucky, I cannot say for lack of experience. But my idea to separate the flying monster from the tank monster using a cube paid off.
Since I just bought the card, I haven't been able to use it very often, but I'll definitely use it more often in my fights in the future.
