Not all that impressive either, until you realize that it is a snipe

I dont know if its the best card overall, but considering the price tag of this card and that it wasnt reprinted outside of a Commander set, people will certainly rejoice when seeing all the different versions of this card in booster packs

I suppose that an argument could be made with Training Grounds, but that is too much just to make the Kefnet the Mindful ability more cost effective

Voja is a 5/5 Wolf with vigilance, trample, and ward and every time he attacks, he puts +1/+1 counters on every creature you control equal to the number of Elves you control, then draws you a card for each Wolf you control

Pretty simple, right
