There is a Reroll button for a reason. Use it generously. If you don’t have the hero bench to take down Guin tanks, find someone who isn’t using Guin.
@InsaneEmu you mention making thousands of summons and not getting Guin or Alberich. You do understand that these are both limited release heroes? Alberich was the Hero of the Month last September; Guinevere is Queen of Avalon and only available during that event from the Event Summons.
