Lady Jaina Proudmoore

Cone of Cold — When Jaina Proudmoore enters
the battlefield tap all creatures target player
controls. Those creatures don't untap during that player's next untap step.
Tides of War — Whenever you cast a
non-creature spell, create an X/X blue Water Elemental creature token, where X is the mana
value of that spell.
"Beware, beware...of me."
