Betsy Specialization (You may only have this in your deck if your hero is Betsy.)
Action -- Destroy a Gold you control: Your next attack this turn gets "When this attacks a hero, wager a Might and a Vigor token with them." Go again (When the chain link resolves, if the attack hit, you create a Might and a Vigor token, otherwise they create one of each.)
Temper (When the combat chain closes, if this defended, put a -1{d} counter on it, then if it has 0{d}, destroy it.)
