cards that you can have any number of mtg Fifth Dawn Uncommon Relentless Rats #58 A deck can have any number of cards named Relentless Rats. The "Any number of cards"

That makes it a 5-color card, in terms of Commander

At Level 1 it can allow you to roll additional dice for your dice roll abilities and at Level 2 it can give one of your creatures +2/+0 and Menace to help get in for some damage

this could be from cards like Toothy, Imaginary Friend and Kianne, Corrupted Memory that grow whenever you draw cards or from those like Psychosis Crawler and Tishana, Voice of Thunder whose power and toughness are equal to the number of cards in your hand

VS Colorless Ramp Out: In: Honestly, it doesnt take much to beat this deck
