Wilbur, Feline Guardian

Vigilance (Wilbur doesn't tap when attacking.)
Cat's Grace -When Wilbur enters the battlefield, you gain 2 life.
Feline Watch -Whenever an opponent casts a spell that targets Wilbur, you may pay {1}. If you do, counter that spell unless its controller pays an additional {2}.
"With eyes of verdant green, Wilbur stands sentinel, a guardian of realms unknown."
