Last Minute Modifier Ideas

Instead of having x2 Elixir every match in the last minute, why not add some variety. Here are some of my ideas.

x3 Elixir - Gain Elixir 3 times as fast. Switch - You switch decks with your opponent Countdown - Towers lose 1% total health each second. Rage Up - Towers gain a permanent rage effect Iced Towers - Towers shoot 35% more slowly Double Value - Cards are half price Slow Elixir - Gain Elixir 2 times slower. Double Damage - Everything (except rocket) deals double damage Break the Bridge - The bridge collapses every 30 seconds for 10 seconds, killing all units on top of it.
