Magic The Gathering Cards of types 'Legendary' and 'Juggernaut'

At the beginning of your upkeep, sacrifice The Great Juggernaut unless you discard a card. Whenever The Great Juggernaut attacks, shuffle your library then exile the top card of your library. You may play that card without paying its mana cost this turn.

Juggernauts you control attack each combat if able. Juggernauts you control can't be blocked by Walls. Other creatures you control have base power and toughness 5/3 and are Juggernauts in addition to their other creature types.
