It is a one-mana legendary monkey pirate creature at 2/2 that, when it deals combat damage to an opposing player, creates a treasure token and exiles the top card of the defending player's library, and you can cast that card until the end of the turn
It's still pretty effective in Commander though, where it can downgrade a huge problem, or take a commander mostly out of commission
Bladewing can bring back another Dragon creature from the graveyard straight to the battlefield, a two-for-one deal that Commander players won't usually pass up
Activating it targeting a creature that has already been blocked will not cause that creature to become unblocked
Other foretell cards will often announce what you likely have in hand, like Iron Verdict
Several of the invitational cards would go onto much acclaim, but sadly a few would disappear into obscurity and not see much tournament play
