I love the Splinterlands Share your Battle.
Many people has great strategies and I learn a lot thanks to them.
I want to participate but it was really complicated for me to use this card and win battles.
My best option was to use the card with DRAKE OF ARNAK summoner :P
The +1 armor helps a lot, also this card may be very useful at a second place because it has 5 life and you can use it as a wall ;)
Here's the team I've used in a 17 mana cap battle:

It was a great because the last to cards wasn't necessary and I've kept all the cards when the battle ends, they could beat to a couple of cards more.
I think this card could be usefull as a supporter for a great first card.
I'll try to use it more on next battles ;)
