The fighting ability is already strong, but it also has a second ability that puts counters on it and makes it indestructible
Fangs is one of the best green cards in MTG to solve that problem
Evolutionary Leap (Foil Rare) I feel reasonably confident that this is a card that will earn a spike within the next 2-3 years
For two mana you get a 2/2 Otter Wizard that deals a single point of damage to each opponent when you cast a noncreature spell
Whenever one or more creatures you control deal combat damage to a player, create a Tarmogoyf token
Getting 2/2s simply for playing Magic is a strong ability on its own, and opens up options for mana ramp, Voltron (making 1 creature super strong through powerups), Curses like Curse of Opulence for table politicking, and several other cool, unique effects that Auras can bring to the table as you build a token army
