It helps when the enemy is a mage, of course, but through sheer grit we pulled through even though the first 10 minutes was 3 people too busy lipping off and dying or staying at the fountain out of spite for not wanting to play with this champion.
Previous game was a really close but yet not really kind of loss based off the fact I had to guide people who were at least willing to try from the very start and I was telling them how to play him. Magic resist, tenacity, don't waste mana on trying to poke skillshots you were going to miss unless you needed zoning to CS a little, that sort of thing. Sadly, Brand stuns were just too much in the end with the semi-organized goings but we all had fun that game.
This one may have been hard going but the fact is, we did it, and now I can happily play with the knowledge you CAN band together under a champion that is not considered the most abusive of mechanics and still win.
Good luck, everyone!
