Hello! Please note that this deck is 100% not tuned, and might be terrible, but might be fun and can allow you to play INFINITE UNITS, if you are so inclined.
I discovered this quirk as a result of the gauntlet boss perk which gives all units BOND. I was playing an unleash deck and discovered that unleash + bond has the very real possibility of going infinite, and soon after I started trying to make it into a deck. You might have assumed there was some protection in place with unleash to make it play nice with bondand not go infinite, but this is not the case. If a unit has both bond and unleash, and a cost equal to or lower than its attack, you can just play them endlessly for 0 cost.
Your options are pretty limited to exploit this, as there is no way to give a unit bond, and only 1 way to give bond units unleash, Valley Whisperer (as far as I can tell, maybe I've missed something).
So I put together this list, and I've barely tested it, though the combo definitely can happen... it might be terrible, but I thought the concept was worth sharing.
