Each time a mulligan is performed, the opposite player may elect to draw an extra card
There are only eight Vehicles in the deck, so that's situational, but still a nice backup option
It doesn't copy any information about the object the card was before it was put into a graveyard
In this deck, I dont think thats an issue, because I think youll always have plenty of targets in your graveyard once you have enough mana to make it powerful, so I like Raise the Alarm here even though I didnt use it in other places
You combine a little combat and removal like Deadly Precision to easily get Sephiroth to a strong state and card engine
At the beginning of your end step, if equipped creature didnt deal combat damage to a creature this turn, sacrifice it
