Diz / Neutral Battle Pet / 2 Mana / 0-2
Cannot be Attacked. All nearby units and generals are temporarily dispelled.
Battlepets are a really underexplored mechanic. Yet they are unique to Duelyst, and cannot be easily replicated in traditional CCGs.
The only ones that are played are just uninteresting stats-sticks. So here's one that isn't. It has a unique effect which could lead to interesting counterplay. Instead of dispelling a unit (all units) completely, this dispel only lasts as long as Diz is alive and nearby.
Diz could kill damaged buffed units like a typical dispel. But units that aren't killed by dispel would regain their stats and abilities if they move away from Diz.
Diz having 0-attack is fundamental to how it works, it is not just a arbitrary balance decision. Making it 1-attack would break him and he would suicide on the nearest enemy.
As Diz has 0-attack, it will not attack on its turn, so will not be counter-attacked. This means that the enemy can kite Diz, and could cause it to backfire on the person who played it - they may find it even more difficult to kill as their offensive spells may only target enemy units.
Stats-wise, I was inspired by Panddo, Ephemeral Shroud & Lightbender
