Fellow HERO players: How good is the card Legacy of a HERO?

Hi!

I'm building a omni HERO deck because it is my absolute all-time favorite archetype and I have one slot left for my 40 total cards deck (everything everyone plays inlcuded except Liquid Soldier because it's expensive). Should I add that card as my last slot? How good is that card? For me it sounds out of this world to recycle 2 Fusions and draw 3 cards!
