mtg cards that you can have any number of Wizards the Coast Relentless Rats This is of the C rarity. o:"a deck can have any

Getting seven cards deep in two turns with cycling and Glimmer of Genius is also pretty easy, and surviving with seven extra life isnt that big a deal

My favorite of this bunch is Shamanic Revelation

What if I told you that not only was that possible, but that for every card you didnt play, it got put in your yard and you got to make an Eldrazi Scion, perfect for chump blocking or using for bursts of extra mana

Game Rant

In something like a midrange deck you are basically never going to use it on yourself to enable some synergy as it is so low value

While MTG Arena used to be limited in its formats, its really grown since its release in 2019
