Make a bunch of treasure and play a bunch of rocks. Then play a ton of land wipe effects. Now you are drawing tons of cards and your opponent is struggling to play the game.
Removing commander color restriction would be really bad for the game. A number of people at my lgs already just run 5 color good stuff using progenitus or child of alara. Removing that restriction would just let them play a hyper utility commander AND their 5 color goodness. I don't need to see a kiki jiki resto angel combo deck piloted by something like Azusa. No thank you. Removing restrictions would just punish people not willing to play 5 or 4 color decks that just run all the best cards. It just promotes the wallet arms race.
Would a cryptolith rite into a wolfbriar elemental be out of the question? Also the metallurgic mimic or w/e his name is from kaladesh would be funny. Name wolf with your robot and now you have a wolf robot that pumps other wolves.
Imagine the tempo 4 of these can give. 4 bounces that late game allow you to directly hurt their hand. This seems like the kind of card that ends up forcing your opponent to end up playing top deck only magic.
Just put a hapatra on field problem solved.
"I put a neg counter on a scarab now I make 1 million snakes by killing 1 million scarabs" then put a counter on hapatra or an enemy to end the cycle. Bonus points for parralel lives(not even needed) and something like kaladesh's green instant give my stuff hexproof and indestructible (bonus if thats on an iso sceptor :D)
New crop mate exert guy that fetches 2 cmc creatures to field from grave is fun with a selfless spririt. Especially if you can make him vigilant for cheap. Then you just have a selfless spirit every combat phase to sac out and make the field indestructible.
Edit got my growths wtong initially
