The Purple Cards-Cursed Items

Player's King characters are able to enjoy all the comforts and advantages of the Blue Card's magic items.
But what about their army's pieces?
Cursed cards offer similar advantages to player's army pieces... for a price!
Allow Rooks to fire shots of power and then live in the shoes of a Pawn. Or, have a Bishop become invincible for a turn or two just to be stuck for another turn or two. Knights can even use magic... to the cost of their own demise!
Your army's pieces craved the power of the King characters and now they have it... and all the consequences that follow!
