'Raven's Seductive Straddle'

Give an enemy card Blue Balls (-1 attack for each turn it doesn't attack, up to -3). 'Let's see how long you last, darling.'

If this card attacks and survives, add a Lube Leak (0/4) to your opponent's deck. 'A little friction never hurt anyone... much.'

Draw a card. 'I may be gone, but the fun's just beginning.'

+1 attack when attacking a card with Blue Balls. 'I love a challenge.'
