lmfao. It is retarded, and bad. But here you go:
1. Horn of the Yeti
2. Inner Grace (gonna get some fast yetis goin')
3. Heal. (for yourself) / Morale (get heal if you're getting hit alot, get morale if you aren't
4. Horn of the Yeti
5. Inner Grace II
7. Horn of the Yeti
8. Inner Grace
Magnificent Presence and Healing Wind are also pretty good, I don't even both with an interrupt because they are totally overrated and your yetis should pave the way.
Favor: I'd go with Horn. I tried Ring and Swift Anklet, Ring is OKAY but because your yetis are so big and slow and cost so much mana, I'd go with Horn to keeep them alive.
Siege Demolishers (Archers IV)
Twig of Life / Wand of Speed
Gloves of Fel-Darkur
Reasons: You might be tempted to get a helm or some armor, but that just stops you from getting Demolishers early. Also, the only spell you should ever really be casting is yetis, which is done at the crystal.
How to Play: Run around and cap flags. Keep your minions around. Sick em on people who get close. Engage with Sedna if their hp drops below 1000 and it should be a kill. Otherwise, run around and cap flags. As always, once you get siege demolishers, stick em to towers. Bishops help too, but only if you're rich.
I can't really write any good strategies, just treat it like an oak minion build with really terrible minions and crazy hp regen and speed.
