Nice combo! Now that you mention it, Shaman just got a card that summons copies of all your minions in hand and then kills them. Maybe that could be used for a boar deck?
Should be possible. Silas + Ashtongue + Marrowgar with a TON of corpses would do the trick with enough mana discounts from Thaurissan (Zola + Enchanter) The trick is getting enough corpses to summon a 30/30 (35/35). It would be easiest if you could fill 5/7 board spaces on the combo turn (So all of the corpses buff a single minion), though I can't think of an easy way to add 3 minions to the board (Since 2 will be Silas and whatever you swapped from your opponent) Without a way to fill the board to buff a single minion, you'd need ~60 corpses to get an average of 30/30 among the 4 minions or ~68 to get an average of 35/35. Which is tricky, but possible with a bunch of tokens (Too bad Patrons got nerfed otherwise Spammy + Grim Patron would have been a nice way to farm corpses)
