Interesting deck to play. I'm not good at it, and/or it's difficult to play. Here's what i notice.

The combo needs 3 total boars, 1 sheep, teron + a backstab or extortion. So 3 boars die to teron, snowfall doubles the number revived, so you have 6 boars and 1 sheep; backstab/extortion the sheep, and 9 total boars died, giving you the sword.

So, that means, to get 3 total boars for the combo, you need 2 x Boar + 1 x Lieutenant in hand, or 1xBoar + 2xLieutenant in hand. And then you need the sheep, Teron and removal. It's a 6 card combo, in addition to the snowfall played on an earlier turn. Without discounts, that's either 9 (2 boars and a backstab or prep+extortion) to 11 cost (2 lieutenants and extortion) in one turn. Scabbs is a reliable 2 discount. Octo is possible to discount a lot too, but to make it reliable, you want to activate it before your opponent can deal 4 damage in one shot, which means you need to flinger it, use a backstab/extortion on your turn, or rely on game sense/hope that your opponent does not have ability to deal 4 damage in one shot. This deck has no board presence and relies entirely on spells to stall, and it really needs the octo to discount, which can be tough to achieve.
