To win all badges easily make a custom deck with those cards :
Imperatively : phoenix, the main's cards of this strategy because phoenix will become immortal when you have 10 or more firepower, so it can tank a line to infinity.
But phoenix is expensive (7 air power) and we need to survive meanwhile to have enough phoenix to win.
For this purpose add : Rejuvenation, for healing.
Meditation, Merfolk Apostate, Merfolk Elder for boost fire and air power generation.
You can choose the chronomancer for the ChronoEngine who allows you to have an extra turn each turn (stack able), it will help you a lot for power generation.
All other cards are optionals, but I recommend to pick Wall of Fire (useful to kill little creatures cards), Stone Rain, Acidic Rain (to kill every creature on the battle) and Armagedon (kills creature and damage opponents, but use able only with 21 or more firepower or phoenix will die).
At least elven Healer and Chrono Hunter could be useful to tank in early.
Enjoy
