Budget Arena - Mono Green - WAR (Standard)

Working on a budget mono green deck to play on MTG Arena for my kids who are on a super limited budget, but I want it to be fun for them. All they have so far are the starter decks the three mythic's from the code given out this week (MYTHICMAGIC). and the free packs from the codes so far (codes listed below).

Restrictions so as not to make the decks too powerful and get into queues with tier decks:
No more than 5 rares and 1 mythic.

PLEASE feel free to provide suggestions, I plan on doing a series of these

PlayAllegiance: Redeems for three Ravnica Allegiance packs. (Expires July 1, 2020)
PlayRavnica: Redeems for three Guilds of Ravnica packs. (Expires July 1, 2020)
