Volcano Hellion enters the battlefield, triggering itself, targeting any creature.
In response, cast
Arcbond by paying ({2} magic symbol) ({R} magic symbol) , targeting the same creature and creating a delayed triggered ability.
Resolve
Volcano Hellion's trigger, dealing an arbitrarily large amount of damage to the targeted creature and to you, which does not cause you to lose the game due to
Gideon of the Trials's emblem.
Arcbond's delayed triggered ability triggers, dealing an equal amount of damage to all other creatures and all players, which again does not cause you to lose the game.
