Lore Summary: A 593-year-old dragonborn named Rosa Phireth is the youngest matriarch to be selected to head the Church of Helios. She carries Ataraxia, the Dragon Warden Staff, which has the power to bend time to the will of its wielder. During a sermon in Matriarchs' Square, an elderly dragonborn interrupts the service, invoking the Brood Mother Yrsiss.
The congregation is outraged, and halberdiers move to apprehend the interloper. Rosa steps to the edge of the dais, and the elderly dragonborn is brought before her. He traces a pagan ward across his chest and pleads for Yrsiss's protection. Rosa reminds the crowd that the dragonborn are free to choose their own path but not under compulsion.
She lifts Ataraxia and tells the dragonborn to place his hand on it, revealing the truth. He touches the staff and is consumed by flames, leaving nothing behind but ash. Rosa declares that Helios has spoken, and they should always trust in him to protect them from the blasphemous.
Strategy
The Helios Matriarch card has the ability Gladiator(Allow the use of one additional Gladiator card in battle), this ability is very interesting because every cards gladiator it has Bloodlust(every time this Monster defeats an opponent, it gets +1 to all stats), and has powerful cards like Quora, tatiana, and many others cards.
Because of that and be a Summoner Dragon, The Helios Matriarch has several strategies. In this Battle, Helios Matriarch allowed me to use the card, i not have Quora, but i have Katrelba, the only gladiator card that has three skills in level one. I used one monster with Taunt for Katrelba not died before use Bloodlust ability.
Summary: This battle took place in the silver league, usually in silver league battles with a lot of mana it's good to put monsters with a lot of attack, but this time I chose to use a slightly different strategy, keep the opponent's monsters as far away from Katrelba as possible for her able to activate bloodlust. If the opponent had put the monsters with the most life point in the last position I would not have won, so this strategy is not very efficient, I ended up getting lucky.
