Polar Barbearian

When Polar Barbearian attacks, stand up, and throw Polar Barbearian into the air, then return
it on the battlefield tapped and attacking. Polar Barbearian gains +X/+X until end of turn,
where X is the number of times you managed to
say "Polar Barbearian" before it lands. If you managed to say "Polar Barbearian" 10 times this way, you win the game instead.
Other players cannot cast Bear Pun spells.
