#7ブラックパンサー、ティ・チャラ

Whenever T'Challa enters or attacks, create a tapped Vibranium token. (It's an artifact with indestructible and "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.") Whenever you cast an artifact spell with mana value 4 or greater, put two +1/+1 counters on T'Challa.
