mtg you can have any number of cards Breaking the Singleton Rule in Commander The "Any number of cards"

This allows you to have a lot of extra mana, and all you need to do is make sure you have life, which is really easy to do when you have a big old lifelink commander

Even if Force of Negation isnt heavily played at the moment, I feel this card will be omnipresent in the future of Modern forever, because every time a spell based deck will be popular, you will have access to the perfect tool to fight them

You only need to choose two cards on your turn

Mana Geode

Unburial Rites + Rite of the Moth Whites great at small-creature recursion, and blacks the king of reanimation, so it makes sense that youd see some powerful reanimation effects when you combine the two

It'll make a five color legendary leader blow up the board, and others will adore it all day long
