Happy Mother's Day (or as my family calls it, Forced Consumerism Day)! This is my personal favourite mother card. Once this thing hits the field, your opponents need to have a solution to it before the end of your combat step. If you have this card and her son (I think) Seshiro the Anointed, you'll easily be able to cast all those cards you just drew. Even though it costs 6, it's still a really nice creature for what it does. I actually don't have any issues with it outside of it only being a 3/3. I'd have like a 3/5 or a 4/4, but I won't complain too much.
Pros: Gives tons of free mana
Cons: 3/3 for 6, requires creatures to deal combat damage to players
