Cards like Courser of Kruphix and Tireless Tracker are exceptional here but will be snatched up by any green deck, so it might be good for some of those payoffs to demand/reward a stronger commitment I'd consider Wayward Swordtooth as a more balanced version of the extra lands effect with a subgame that's fun and attainable (and not just by you!) #3 I think Simic Lands is a great archetype that won't be leaving my cube any time soon
Past Standard examples include: Fable of the Mirror Breaker, Atraxa Grand Unifier, or Raffine Scheming Seer
Mirko Vosk, Mind Drinker $1.50 Every time this hits, you get to cast Mind Funeral, a three mana spell
That means that theres a decent chance at least one player in a game of Commander wont be able to block the creature this is attached to, giving you an easy route to untap your lands
Two of these cards are guaranteed to have a rarity of rare or higher
Creatures with Horsemanship can only be blocked by other creatures with Horsemanship (But can block creatures that don't have Horsemanship)
