Raffine, Scheming Seer Raffine, Scheming Seer is a significant option for a discard commander because of the sheer number of cards it pitches
This deck doesnt have any infinite combos (though, knowing +1/+1 counter decks, I may have missed one), but it can turn a board with a dork and Animar into a massive mess of creatures
Yes it extends the game by quite a lot
Courtesy of The Mana Source, Exotic Orchard is a land that can be tapped to produce mana of any color that your opponent's lands could produce (so if your opponent only has Plains, it can only produce White mana, but if they have a Steam Vents it can produce Blue or Red mana)
It may end up too slow for Standard, but youd be a fool to bet against this angsty Assassin in Commander
