Cloned from Partner and Commander

So basically this is a (mainly) 4 player multiplayer commander cube.

Trying to seed with enough commander options to just draft and have fun with bombs.

Would also like this to be viable 1v1, but less important than 4 player commander.

There are two custom rules in here

All legendaries without partner also have partner

All planeswalkers that can be a commander without partner have partner

All players also start with a sol ring, an evolving wilds, a commander's sphere, and an arcane signet during deck-building.

This should let people be able to make some fun builds
