Big Bang
RegentSkillRare
For 0 Energy: draw 1 card, gain 1 Star, gain 1 Energy, then Forge 5, and the card exhausts. Everything is front-loaded, so it replaces itself, nets 1 Energy, and either creates your Sovereign Blade with 15 damage or adds 5 to the Blade you already have. Upgrading adds Innate, so it is in your opening hand every fight.
When to take Big Bang
Take it in any Regent deck, a free card that adds Energy and builds your Blade is never bad. Upgrade it at the first chance, since a guaranteed turn 1 Blade changes how fights start.
