Whenever one or more creatures you control deal combat damage to a player, you draw a card and lose 1 life
You may reveal a card with assist kicker and discuss how to pay for it before you begin to cast the spell
These decks would thrive off the combo of Vein Ripper and Sorin, Imperious Bloodlord
Much to my wife's chagrin, I tend to organize my collection via the "tossing the cards in whatever box happens to be nearby" method, which is not recommended
That's a great way to cast any legendary creature, and for other spells, Delighted Halfing can simply tap for one colorless mana so it's not restricted to casting legendary creatures
That doesn't even cover the chaos roll effect either, which is just good old-fashioned bread and butter value everyone can enjoy
