You can always use cards like Liberator, Urza's Battlethopter or Leyline of Anticipation to change the casting speed
The wacky combo with this deck is something that allows you to fight one of your own creatures, Broodhatch Nantuko (or Saber Ants), and Purphoros, God of the Forge (okay, there are lots of things that combo with Purphoros)
For starters, this creature gets +1/+0 for every artifact you control, making it a very power-heavy card in some decks
Rules Lawyer, you can't do that
That means our opponent probably wont attack with the other 4/4if wed rather eat one of the 4/4s and dont mind taking 4 damage, we can Dream's Grip instead after attackers are declared
Theres nothing like a good meal, and no one makes food like a Hobbit
