Since there is no way to kill creatures, I'm assuming you aren't planning on refreshing the bone wall?
Interesting really, except the strategy is broken if the enemy has two CC and plays wisely. Also, you have no PC.
This is a generally basic strategy which can be seen coming as soon as you play mitosis on your scorpion or dragon.
However, if the enemy has no CC or shields and can't outrush you, they are pretty much screwed.
The meta of this game as of this point involves almost every deck having one method of killing creatures.
Also, a huge fraction of the decks have shields at the moment.
Another also, those decks that have neither make up for it with speed.
That said, this has a hard time in PvP.
I will give this deck 5/10 stars. It's original but not very effective in the PvP world.
