Sacrifice three artifacts you control: Each player exiles the top card of their library. You may choose a creature card from among them and create a token copy of that creature with haste and trample onto the battlefield tapped and attacking. Sacrifice that token
at the end of your turn. Put all cards exiled this way
on the bottom of their owner's library. You can only activate this ability when you declare attackers and only once on each of your turns.
