Well I only consider her useful in very fast tourney. Maybe you could tank her in a non Holy tourney.
But for Very Fast I’d rather tank Chochin or Bjorn. I’d even consider Gunnar. I emblem my threes so I won’t use an unemblemed three star. And I wouldn’t use emblems on Gill-Ra just for no Holy very fast tourneys.
Two 3 star no Holy Rush tourneys ago you see several gunnars in top 10
