Notes & Combos
If you have it, I would probably include Swift Gaia the Fierce Knight. I don't so I'm using YamiROOOLAH!
The Warrior Returning Alive is a decent choice for Legend spell but isn't strictly needed thanks to Icezark + the skill letting you get out 3k beater in Icezark itself and one of your 7 star warriors of choice.
You can't send Buster Blader to the grave with the skill so you must draw it. Buster Blader is the target of choice with Icezark, but if he isn't accessible then Semeruler is preferred because his effect is useless and the other Rulers can only activate when tribute summoned. You don't use their effects often but it's nice to have the option.
