Lumra, Bellow of the Woods is a Legendary Bear with power and toughness eual to the number of lands we control. With Vigilance and Reach it is a great target for placing +1/+1 counters with Ayula, Queen Among Bears and its last ability, can even help us with ramp and have great synergy with Ayula’s Influence as we can firstly discard all the lands from our hand to create an army of bears, only to return them with Lumra, Bellow of the Woods and get great profit! Although I guess it is designed for Lands matter and Land recursion builds, it fits greatly in our Bear Tribal!
Evercoat Ursine is a high mana cost Bear with a great ability that can help us cast spells for free with a limit. With Hidaway 3, hidaway 3 on ETB it exiles 2 cards and we can play them later for free when it is dealing combat damage to a player. With Trample and Ayula, Queen Among Bears that is not hard to achieve and on top of that it may become a potential finisher. Of course it gets even better when its ETB is doubled by Panharmonicon. Great pick for our Bear Tribal build!
The more we enrich our Bear Tribal with Bears with powerful abilities, the more Muraganda Petroglyphs seems less charming so it gets cut.
Patchwork Banner is one of the best cards for Tribal builds as it combines ramp and tribal support. Being both a mana rock and a Tribal Anthem gives us amazing value for its mana cost. Of course it is a top pick for our Bear Tribal!
Vastwood Surge has synergy with our build but it kicker costs a lot and it can’t compete with the utility of Patchwork Banner.
Branching Evolution is now a super budget option thanks to its latest reprints, but remains a very powerful card for +1/+1 counter builds. Of course it works wonders in our Bear Tribal as Ayula, Queen Among Bears can easily put counters on our Bears. It gets crazy if we also add Panharmonicon.
