While some might assume that Breena is a Group Hug commander due to providing card draw to the entire table, she is far from it: yes, your opponents can draw cards off her too, but in exchange you get +1/+1 counters and they had to attack your opponents in the process -- so you will be the one benefitting the most at all times
If that cards mana value is less than or equal to the number of experience counters you have, return it to the battlefield
The first of these is Cavalcade of Calamity, a 2-mana enchantment that deals damage whenever you attack with a creature with power 1 or less
However, anything in Magic that cares about transforming things treats "Convert" as the same thing as "Transform"
Youd be surprised how easy it is to upgrade your starter decks to be a bit more competitive in the meta with just a couple changes
It's a bit too overpriced for Modern, but it's very tasty in Commander
