We wanted a card that can be used to stun/disable enemies in exchange of high cost like 4 or 5 points but we also need to have increase the Stamina pool too. 10 stamina with some new addition cards also will take toll on tougher enemies, it should be increased via Skill Stats too (5 points should be enough).
Provoke or taunt can be added when we have some companion joined the battle too but it will be very long time before we can see them for sure.
