The 10th Mage Saint, Makarov

All Saints have "Whenever this creature
transforms or attacks, each opponent discards
a card, then each opponent who didn't discard
a non-land card this way looses 3 life.
{5}{w}{w}: Destroy all non-NAKAMA creatures.
(All Guild cards are our NAKAMA)
"You were the greatest family anyone could ever ask
for. Thank you, and take care of each other!"
