Players can't draw cards, Players can't cast noncreature spells exiled by Omen Machine, Lock
At the beginning of each draw step, Omen Machine prevents the active player from drawing a card, and causes them to exile the top card of their library, and cast that card if its a spell without paying its mana cost, or put it onto the battlefield if it's a land.
If a player casts a spell this way, Vexing Bauble triggers, countering that spell.
