Ward—discard your hand; if you discard less than three cards, mill ten cards, otherwise mill five instead.

If an opponent would draw a card, and it isn't the first card they drew this turn, they mill two cards instead.

If an opponent would put a land into play, and it isn't the first land they played this turn, they discard that card and you may search your library for a basic land and put it into play, then shuffle your library.
