Augur of Argument

Flash
When Augur of Argument enters the battlefield,
each player may reveal a non land card.
Choose any number of spells revealed this way
and exile them. You are dealt {x} damage, where {x} is the total converted mana cost of all cards
exiled by Augur of Argument's ability. You may
cast spells exiled this way without paying their
mana cost and as though they had flash for as
long as you control Augur of Argument.
