Since releasing the demo, we realized a few things about the Flying mechanic. 

1. It's hard to understand. 
2. It's not very exciting! 

In the full release, we're changing how Flying minions work to solve both of these problems. Flying will have the following text:

This means that Flying minions will have the chance to dive out of the way each time they are attacked, resulting in neither the Flying minion or its attacker being damaged. Here it is in action:

The end result is a mechanic which is much easier to understand and makes for more excitement in battles. It also means that we can add new cards and relics that interact with dodging!

There's one other new relic that synergizes with dodging, but we'll keep that a secret for now.
