Worked well, except saying under 463 is a little deceiving, after killing the snake and pressing surge of power to use against Breaker he moves first and when he doesn't crit I was lucky to still be alive with 3 health. His non crit first hit is 525 everytime so strat should state to use surge of power as soon as snake is dead. Surge and moonfire from fairie killed breaker leaving about 4 arcane blasts to kill the frog.
Only change I made was passing in Turn 1, since Blinding Poison does no damage
Ancient Blessing Turn 2, since you still have Blinding Poison and can't hit, anyway.
For everything else I followed the strat, and it worked just as described.
On another try I skipped Life Exchange, *but* I have the P/B breed, so a touch more HP and power than some breeds. Also, skipping Life Exchange only worked if I wasn't frogged on Turn 3 with Stickers. Therefore, using Life Exchange was safer and guaranteed more success with using just 2 pets.
