This is a Tundra Rhino OTK that uses Tavish and Tame Beast (Rank 3 of course) to summon out 2 Dire Frenzied Young Dragonhawks to attack for 32 damage. You could do this as soon as turn 7, but then you'd only deal 28 damage. You can still pull it off if you pulled Tundra Rhino with Scavenger's Ingenuity.
Step 1: Draw the following combo pieces: Dire Frenzy, Tavish, both Tame Beasts, Tundra Rhino, Scarlet Webweaver, and Young Dragonhawk
Step 2: Use Dire Frenzy on Young Dragonhawk. You want to do this step just before you go for the OTK to reduce the odds of drawing more than one of your Dragonhawks.
Step 3: Use Scarlet Webweaver to discount Tundra Rhino. These steps are interchangeable, depending on your current hand.
Step 4: Wait until turn 10. If you drew Tundra with Scavenger's Ingenuity or your opponent can't heal over 28 damage, you can OTK as soon as turn 7.
Step 5: Tavish > Tundra (2) > Tame Beasts (6)x2 > Dire Frenzied Y. Dragonhawks (4x2)x2 = 32 damage
I swear you can climb out of Wild Bronze with this deck. Maaaaybe Iron if you're really good.
