mtg strefan commander deck Magic The Gathering - Innistrad - Crimson Vow you may put a Vampire card from your hand onto the battlefield tapped and attacking Magic: The Gathering Innistrad: Crimson

In my experience, World Shaper is actually a little short on cards with that effect (surprising since the entire point of the deck is to sacrifice all your lands), so Id also consider adding in a few other spells with a similar ability

When this creature leaves the battlefield, the exiled card's owner creates an X/X blue Illusion creature token, where X is the mana value of the exiled card

That means if you play a 6/6 dragon with some absurd ability, you then have two copies of that dragon until the end of the turn

[card]True-Name Nemesis[/card] [D+]/[A+] The card that has all the EDH players up in arms over making Mind Seize scarce and overpriced is ironically not very good in the format it was supposedly designed for
