I personally would only run it in decks that really care about a specific ability it provides
Ive not played the decks yet, for obvious reasons
The tradeoff is that the copies disappear at end of turn, so be sure to make their brief presence felt
Whenever Voja attacks, you put X +1/+1 counters on each creature you control, where X is the number of Elves you control, then you draw a card for each Wolf you control
For an aggressive deck, mono-green has a lot of staying power: Icetill Explorer lets us play more lands, Sapling Nursery creates 3/4 tokens, and Earthbenders Ascension keeps adding more +1/+1 counters on creatures
Instead of doubling your draw, you turn a single draw into two impulse draws
