Primal Force

IroncladSkillRare
Transform all Attacks in your Hand into Giant Rock.

A free Skill that replaces every Attack in your hand with a Giant Rock: a 1-cost Attack for 16 damage, or Giant Rock+ for 20 when Primal Force is upgraded. The code makes a fresh Rock for each transformable Attack and swaps it in, so the original card's other text is gone.

When to take Primal Force
