Issue with Captain America, First Avenger

**Describe the bug**
When you activate the Catch ability the first thing you are asked is "Choose X for Captain America, First Avenger" this choice is not at all clear what it's for and the limit is unbound. If I wanted to I could choose 200 (and I did for a test.) When doing this you still pay the mana, but the ability does nothing.

**Expected behavior**
To select an equipment to unattach first, choose targets (which would be bound to the maximum amount of damage possible, but not more than 3), pay {3}, then divide the damage amongst the targets.
