If you wanted to actually use "bears", there are quit a few options to make them lolz face your opponent.
Ashcoat Bear - This guy should be considered, flash is an amazing ability that has leaked into the green color pie. With some of the other cards that I will be listing you will quickly see why playing another bear at instant speed will be highly useful.
Spectral Bears - Auto-include if the people at your kitchen table are black players. Great include against those zombies decks.
Werebear - great mana acceleration early game. He's a bit weaker than most of his cousins until you get seven cards into your graveyard, but I like him.
Caller of the Claw - Great creature to include to protect you against board sweepers.
Ok, those are the other "bear" cards that I would like to include in the list.
Now onto some win conditions.Door of Destinies - It's a little slow, but with a werebear or other mana ramp you can play it easily on turn three. From then on its +1/+1 for each bear that comes out.
Coat of Arms - This card is silly amazing. I would take it out if your opponents are playing tribal decks as well, because it effects all creatures, not just the ones you control.
Epic Proportions - It's a fun combat trick that gets to stay on the creature. I've always liked this card in the casual formats.
Muraganda Petroglyphs As mentioned before with the simple zero ability bears this is amazing.
Overrun - A classic finisher
Utility cards, ones that protect and destroy lands, artifacts, or enchantments.Asceticism - This card is amazing in slower formats. Giving all your creatures hexproof and the ability to regenerate for 1G is amazing.
Storm Front - A great card to use against your buddies that like to use their dragon or angel deck.
Depending on what kind of enchantment/artifacts are in your MtG group I've selected a few that I really enjoy.Nature's Claim - It has a draw back, but it's amazingly cheap and at instant speed. Get rid of pesky artifact creatures when they attack, enchants locking the game, or equipment that gives you a problem.
Krosan Grip - The staple get rid of enchantment or artifact spell.
Crushing Vines - A personal favorite of mine in EDH. It has slew many angels and flying creatures, as well as the occasional artifact. Choices are good.
Bramblecrush I would only play this if planeswalkers or certain lands are a problem at your table, otherwise stick to the cheap instant speed spells.
For those of you that are worried about red spells like
Pyroclasm,
Slagstorm, and sweepers that "Destroy all creatures", but allow regeneration I would suggest
Wrap in Vigor
