If you have a base head equipped, transform it into this, then equip this.
When this transforms from or into an Evo with a different name, your hero gets +1{i} until end of turn. If that Evo is a hero, instead this triggers twice.
Temper (When the combat chain closes, if this defended, put a -1{d} counter on it, then if it has 0{d}, destroy it.)
